Frequently Asked Questions
What is TopCoins?
TopCoins is a skill-based crypto competition platform where you draft crypto portfolios and compete against other players based on real market performance. All prices and data are live from real exchanges.
How do I join a league?
Navigate to the Leagues page, choose a league that suits your budget and strategy, then click 'Join'. You will be taken to the league detail page to draft your portfolio before your entry is confirmed.
How is portfolio performance calculated?
Your drafted portfolio is scored on real-time price performance from Binance and CoinGecko. The percentage gain or loss of each asset in your draft contributes to your overall score for the duration of the league.
How does MetaMask login work?
We use MetaMask's personal_sign to verify wallet ownership. No private keys are shared — you simply sign a unique message to prove you control the wallet.
Are entries verified on-chain?
Yes. Every league entry is hashed and committed to the league's specified blockchain for tamper-proof integrity. You can verify any entry using the 'Verify Hash' link.
How do withdrawals work?
Withdrawals are processed to your TRON (TRC-20 USDT) wallet address. Processing typically takes 10–30 minutes depending on network congestion.
What fees are charged?
TopCoins charges a 15% platform fee on net prize pools. Entry fees vary per league and are shown on each league card. Deposits and withdrawals via crypto are free.
Can I cancel a league entry?
You can cancel before the lock-in timer expires. After lock-in, entries are final and cannot be changed.
