Dunno for sure what might be considered as the best crypto, as I am not really fond of crypto trading but I can state that nowadays traders tend to refuse trading cryptos, as the bitcoin is super volatile these days.
I would advise you to pay attention to etherium or maybe solana.
These are one of the coolest assets for trading, nevertheless always pay attention to risk and money management.
They matter a lot in this case, as we are talking about super volatile assets. The risks are quite high and hence you must be wise enough to make decisions.
