Yes, you can have your purchased cryptocurrencies withdrawn in your BISON account. Just go to »Settings« and click on »Withdraw cryptocurrencies« under »Account«. Please note that if you enter a false wallet address, the withdrawal can no longer be reversed.
Some cryptocurrencies (UNI, LINK, SHIB, AAVE, ALGO, MANA, DOGE, MATIC, SAND) unfortunately cannot be deposited at the moment.
