Introduction
SizeProp review: SizeProp is a crypto-native proprietary trading evaluation platform launched in October 2025 and operated through SIZ EDU Limited in the Cayman Islands. It currently offers Degen, 1-Step and 2-Step evaluations with static maximum drawdown, no consistency rule, no minimum trading days and no standard evaluation time limit. Its proprietary terminal is built around crypto-native market infrastructure and current company materials advertise funded reward splits from 80% to 95%. Prop Firm Bridge rates SizeProp 69 / 100 with PFB Verified status.
SizeProp has attractive trading rules, but the score is intentionally close to the bottom of PFB's Trusted range because of its formal Withdrawal Policy. That document states that rewards are discretionary, meeting eligibility criteria does not guarantee approval and SizeProp may approve, deny, delay, reduce or cancel a request at its discretion. The company also says it is not required to provide an explanation. This legal payout discretion is the single biggest risk in the review.
Bridge Verdict Preview
SizeProp has a strong challenge-rule profile but weaker payout-contract protection. Static drawdown, no consistency, no minimum days and no standard deadline are all trader-friendly. The main reasons it does not score higher are the broad discretionary withdrawal language, short operating history and conflicts between newer live rules and older indexed documents.
TL;DR
- Best for: disciplined crypto traders who value static drawdown and simple evaluation rules.
- Biggest strength: no consistency rule, no minimum days and static maximum drawdown across the core programs.
- Main risk traders must understand: the formal Withdrawal Policy gives SizeProp broad discretion over payout approval even after eligibility conditions are met.

Ratings Breakdown
Our Take
SizeProp received a 69 out of 100 score because its trading rules are genuinely attractive but its contractual payout protection is materially weaker than the highest-ranked crypto firms. Static maximum drawdown, no consistency rule, no minimum trading days and no standard evaluation deadline all score well. The formal Withdrawal Policy is the main reason the rating remains only slightly above PFB's Trusted threshold.
Who This Prop Firm Is For (and Not For)
SizeProp is best for disciplined crypto traders who value simple risk rules. Degen is appropriate only for very low-drawdown systems because the 3% total static limit is narrow. 1-Step is the most balanced single-stage choice. 2-Step offers the widest current static maximum drawdown but requires two separate targets.
SizeProp is less suitable for traders who require strong contractual entitlement to a payout, a long multi-year operating record or a firm whose public legal and rule documents are perfectly synchronized.
Risk Profile Compared to Industry Standards
From a pure trading-rules perspective, SizeProp compares very well with the industry. Static maximum drawdown is easier to manage than trailing drawdown, and the absence of consistency and minimum-day requirements removes common reasons otherwise profitable traders fail.
The risk profile changes once payout rights are considered. The Withdrawal Policy gives the firm broad discretion and states that meeting eligibility conditions does not guarantee approval. PFB treats legal payout protection as part of trader risk, not as a separate technicality.
PFB Verification Signal
PFB prioritizes the current live Our Rules page for active trading mechanics and the formal Withdrawal Policy for payout rights. This is why the review uses the current 8:00 PM UTC reset and equity-enforced rules even though older indexed SizeProp material describes different drawdown behavior. When current and old documents disagree, the freshest governing material receives more weight.
Pros & Cons
| Pros | Cons |
|---|---|
| Static maximum drawdown across current core programs | Withdrawal Policy gives the firm broad payout discretion |
| No consistency rule | Meeting payout eligibility does not guarantee approval |
| No minimum trading days | Policy says an explanation for a decision is not required |
| No standard evaluation time limit | Short operating history since October 2025 |
| Crypto-native Hyperliquid-powered terminal | Older Terms / blog material conflicts with newer rule mechanics |
| 80%ā95% reward range | Degen's 3% total drawdown is very tight |
| Public founder and identifiable Cayman operator | Current negative payout-delay reports exist alongside successful payouts |
| Successful payout evidence exists | Pricing has changed, making old indexed fee tables stale |
In-Depth Review & Analysis
SizeProp is a crypto-native proprietary trading evaluation platform launched in October 2025. Traders pay a one-time evaluation fee for a simulated trading account and attempt to reach the program's profit target without breaching daily-loss or maximum-drawdown rules. Passing creates access to a funded performance-reward account. The formal Withdrawal Policy makes clear that trader activity remains simulated and that rewards are paid from company operational revenue and internal treasury rather than from a trader-owned brokerage account.
Evaluation Models & Account Types
The current SizeProp product family includes Degen, 1-Step and 2-Step. All three use static maximum drawdown and currently have no consistency rule, minimum trading days or standard evaluation deadline. The meaningful differences are profit target and risk allowance.
Model Logic Breakdown
Degen: Degen uses an 8% profit target, 2% daily loss and 3% static maximum drawdown. It is the narrowest current structure. A trader who regularly experiences more than 3% peak-to-trough drawdown should not choose Degen solely because of lower historical pricing.
1-Step: 1-Step uses a 10% target, 3% daily loss and 5% static maximum drawdown. This is the most balanced current single-stage product. It provides materially more room than Degen without adding a second evaluation phase.
2-Step: 2-Step uses a 5% Phase 1 target followed by a 10% Phase 2 target, 4% daily loss and 6% static maximum drawdown. It offers the widest current total loss room but requires the trader to complete two separate targets.
Who Is This For?
Degen is for exceptionally controlled strategies. 1-Step is the strongest all-round choice for traders who want one phase. 2-Step fits traders who prefer the widest current static loss room and are willing to complete two phases.
Pro Tip: choose the account by worst historical drawdown before looking at the fee.
Pricing, Account Sizes & Larger-Account Logic
SizeProp's pricing has changed materially during 2026. Older founder content listed a $100K Degen account at $344, while the September live homepage showed a $580 base price before a temporary official promotion. The current $100K 1-Step base price remained $999 during the audit.
PFB deliberately avoids presenting old May prices as if they were current September checkout values. The live selector should be treated as the final authority for account sizes and fees.
A larger account can improve the percentage risk profile only when dollar risk remains stable. A $150 planned loss is 3% of $5K, 0.6% of $25K and 0.15% of $100K. The same trade becomes farther from the hard account limits as size increases. Increasing the planned loss proportionally removes that advantage.
Trading Rules, Drawdown & Risk Calculations
Rule Overview
SizeProp's current live rules define balance, equity, daily loss, maximum drawdown, profit targets and inactivity in clear language. Balance reflects closed trades. Equity equals balance plus unrealized P&L. Risk thresholds are calculated from balance but enforced continuously using equity.
This means open losses count toward both daily and maximum-loss breaches. Profit targets work differently: profit must be realized in balance to pass the evaluation. An open winning position does not count toward the target until it is closed.
The current daily reset is 8:00 PM UTC. At the reset, the daily dollar limit is recalculated from balance and then remains fixed until the next reset. Maximum drawdown is static from starting balance.
Drawdown Math Explained
On a $100K 1-Step account, 5% static maximum drawdown places the lifetime floor at $95,000. If the account grows to $110,000, the floor remains $95,000. Profit therefore creates real extra lifetime buffer.
The daily limit is separate. A 3% daily loss on $100K creates a $3,000 session boundary based on the relevant reset balance. A trader can breach the daily limit long before the lifetime floor is reached.
Degen is much tighter. On $100K, 3% static maximum drawdown gives only $3,000 of total room, while the daily limit is 2%. This is a precision product, not a cheap beginner account.
Equity vs Balance Logic
Current rules explicitly say open trades always count toward risk limits. This corrects older founder content that described a more balance-only framework. PFB uses the newer live rule page because it is the current product authority.
Traders should monitor floating equity during volatile crypto sessions. A position can breach the account before the trader chooses to close it.
Psychology & Capital Protection
No consistency and no minimum days can create a false sense of freedom. Traders may try to finish quickly because there is no calendar restriction. The static risk limits still require conservative sizing.
Pro Tip: the absence of a consistency rule should reduce unnecessary trading, not encourage more aggressive trading.
No Minimum Days, No Consistency & No Standard Deadline
No Minimum Trading Days
A trader does not need to place filler trades after reaching the target. This is a meaningful advantage because it removes risk that exists solely to satisfy a day counter.
No Consistency Rule
Current rules do not require profit to be spread evenly across days. This fits crypto's naturally lumpy volatility better than 20%, 30% or 40% best-day formulas.
90-Day Activity Rule
There is no standard deadline to complete the evaluation, but the current rules require at least one trade every 90 days to keep the account active. This is an inactivity condition rather than an evaluation-expiry date.
Profit Split & Payout Process
Payout Unlock Logic
The current homepage advertises funded reward splits from 80% to 95% depending on selected configuration. The trader must remain compliant and complete any required verification before a payout can be considered.
The important legal point is that the Withdrawal Policy characterizes rewards as discretionary rather than contractual entitlements. Meeting the listed eligibility conditions does not itself guarantee approval.
First Payout Timeline
Company marketing has referenced fast stablecoin payouts, while the formal Withdrawal Policy preserves manual review and company discretion. PFB therefore avoids converting a marketing processing target into a contractual guarantee.
Payment Methods
Current company materials describe stablecoin rewards, commonly USDT. The exact token, network and processing process should be confirmed in the active dashboard because the policy allows operational changes.
Realistic Payout Expectations
SizeProp has successful payout evidence and a generally positive external review profile, but traders should read the formal policy before purchase. The legal right retained by the company matters most when a dispute occurs.
Withdrawal Policy: The Most Important Risk
Eligibility Does Not Guarantee Approval
The formal Withdrawal Policy states that a trader can request a reward after satisfying funded-account, positive-profit, rule-compliance and verification conditions. It then explicitly says meeting those conditions does not guarantee approval.
Broad Company Discretion
The policy allows SizeProp to approve, deny, delay, reduce or cancel a request for reasons including compliance concerns, suspected rule violations, fraud indicators, failed verification, operational review and internal risk decisions. It also says the company is not required to provide an explanation.
This wording is the main reason PFB's Payout Process sub-score is materially lower than the trading-condition score. A firm can have excellent challenge rules and weaker trader protection at payout.
Trading Platforms & Broker Integration
Platform Stability
SizeProp uses a proprietary crypto-native terminal powered by Hyperliquid market infrastructure. Company material has also referenced other market-data sources. The environment is designed for perpetual traders rather than MetaTrader-first users.
Execution Feel
The platform uses live market data while the trader account remains simulated under the formal policy. Traders should test order behavior, slippage and instrument availability before scaling size.
Spread vs Execution Reality
Trading costs include spread, fees, slippage and funding. A high-turnover strategy should be tested after realistic costs because risk limits are enforced on equity in real time.
Broker / Liquidity Reliability
SizeProp is not a retail broker taking customer deposits. The trader's right is the company-defined performance reward. Hyperliquid-powered data should not be confused with personal ownership of a live Hyperliquid account.
Prohibited Strategies & Hidden Rules
SizeProp's formal Terms contain broad anti-abuse provisions covering latency exploitation, platform bugs, simulation-specific strategies, account misuse and other behavior the firm considers non-replicable or abusive. Exact current bot and copy-trading permissions should be verified in the live FAQ because they can evolve.
Soft Breaches / Risk Warnings:
- Buying Degen only because of historical low pricing
- Believing floating loss does not count
- Using an old reset time from indexed content
- Assuming no consistency rule means payout approval is automatic
- Treating stale May pricing as current
Hard Breaches / Prohibited Conduct:
- Crossing daily or maximum-loss limits
- Account misuse or identity violations
- Latency exploitation or platform-bug abuse
- Other prohibited behavior under the active Terms
Conclusion
SizeProp earns a 69 / 100 PFB Score because the challenge rules are stronger than the payout contract. Static drawdown, no consistency, no minimum days and no standard deadline make the evaluation itself attractive. The formal Withdrawal Policy materially reduces the overall rating because reward approval remains discretionary.
1-Step is the best balanced route for many traders. Degen should only be used by very low-drawdown strategies. 2-Step provides the widest current static risk buffer but requires two targets. Every prospective trader should read the Withdrawal Policy before paying.

Final Verdict
Is SizeProp PFB Verified or Risky for Crypto Traders?
Verdict: PFB Verified ā 69 / 100
SizeProp narrowly clears PFB's Trusted threshold because the current product is active, its trading rules are attractive and successful payout evidence exists.
The decisive caution is contractual payout protection. The formal Withdrawal Policy says rewards are discretionary and that meeting eligibility criteria does not guarantee approval. The company also retains broad authority over payout decisions.
Recommendation: SizeProp can fit disciplined crypto traders who prioritize static drawdown and simple evaluation rules, but traders who require stronger contractual payout entitlement should prefer a higher-ranked firm.
