This is not a promotional post but here's my profitable crypto for 2021
1. Hex - bought around 1 cents and i were able selling my hex with 15x profit but this coin lack of utility even some called this as a suspicious coin.
2. axie - I got capital gain from this coin and i can also get daily SLP and this gives me a daily basis income. It's totally worth to try
I guess there are more NFT coins that's worth to invest.
