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.
Im also still holding my BNB too but i have sold my ethereum and some major coins a few hours ago to anticipate the correction that will be happening very soon.
The exchange site's token always become my favourite altcoin right now. It has real utility usage.
