I will choose BNB in 2021 as an investor, because it has enormous potential, the price will continue to increase, because people will be too tired of ERC20, whose gas fee is too high.
Always remember, never put all your eggs in one basket, divide your investment into 2 or 3 coins at least. So, if you have a loss in one of the coins, then the other coins complete that loss and also give a profit. And i agree people are fed up with eth high fees and are moving away from Erc20 tokens, but we also have other tokens such as Cardano, Polkadot.
