If you wish to go for specific
Crypto Exchange then the obvious choice is Coinbase or Binance, which is what everyone prefers. So that’s really what I will suggest to anyone and there is really no rocket science into what I am suggesting.
However, IF you are looking for a broker then again there are many obvious names like Etoro, Exness and such but got to be work with one you are MOST comfortable with, as that’s really how you are able to gain.
