You can withdraw profits from your funded account at any time. The starting trading balance stays with Kraken — it's the capital you trade with, not money you can withdraw. There's no minimum, no profit withdrawal fee, and you can request withdrawals as often as you like. We do our best to have the withdrawal land in your account within 24 hours.
Withdrawals are in USD, so sell any open crypto holdings first. Once you withdraw, 80% of your profits transfers to your Kraken account balance. Kraken keeps the remaining 20%.
Example: your $10,000 funded account grows to $10,500. That's $500 in profit. You withdraw $400 (80%); Kraken keeps $100 (20%). Your funded balance resets to $10,000 and you keep trading.
