BNB returns and growth were impressive last year. No offense about ETH but personally for me, BNB is a better choice. Till they develop Binance as the exchange BNB as a currency will become stronger as well.
As an investor, we have our choice , but we can actually choose both if we believe on both of them.
Personally, I think Binance has been very consistent, what have they have achieve last year was surpass this year, so I always think of the possible of a new ATH.
