I have bought some bitcoin and other crypto likes MANA, CAKE, DOT, ETH, and many other through USDT and UST
In future If i want to sell it against BUSD or any other stablecoin then is that possible? Means, whenever I sell Bitcoin, MANA, etc.... i get BUSD or other stable coin. Possible?
of course it's possible. as long as the exchange you choose provides that option, then it's very easy. in fact, the purpose of the exchange was for just that. how can you buy a lot of coins but you don't know about the BUSD pair. try checking again on the exchange you chose, or on the popular exchange on coinmarketcap, you will see that.
