Honestly, I'm confused about which is my favorite altcoin. But one thing that is certain is that I make several altcoins my favorites because of their transaction speed and the cheap fees required for transactions. Like Tron. But within the community solid strengths and worth holding onto are ETH and BNB.
And many more based on their different categories and uses that make me like some altcoins.
I can relate with you there that it isn't easy to choose the favorite altcoin. I also don't know which altcoin is my favorite but honestly, I prefer altcoins where it's transaction speed is fast and also the fee is cheap. What I always use is xrp for transferring purposes since it's transaction fee and speed is good. BNB is good too but you can say that's what I will use either BNB, ETH or XRP (most of the time) because it is very cheap especially for people like me who doesn't have lots of crypto.
