I have deposited to Russian-based sports gambling website and there is no such rule to withdraw the same way user has deposited. Whenever I need fiat money, I can deposit cryptocurrencies and withdraw my deposit + winnings to electronic money wallets in less than 20 minutes. If the bookie has no rule about wagering, the user can withdraw the deposit whenever he needs to do so. Of course, I don't suggest doing this in well-known gambling platforms your account will instantly be blocked due to the suspicious activity but you can do it on small gambling websites. So make your choices smartly if you look for something specific.
