I don't know which one to buy, because you know that getting profit from coin eth and btc is very difficult, especially for small fund of users. I am even more interested in some coins that have a smaller value but have good potential, for example BNB and TRX. But when viewed from the experts' talk and information that ETH is experiencing a setback while bitcoin will halving in the coming months, so bitcoin might have more potential, if I would choose bitcoin.
