My favorite is cryptocurrency. Which I have already hold. My favorite cryptocurrencies are BTC, ETH, BNB, LTC, Doge coin. I got a lot of benefits from BNB and Doge. When I bought BNB, the price was low. A few days later the price of BNB coin went up overnight. So BNB is my most favorite coin. You can also buy BNB coin if you want.
