Putting everything into crypto for me is not the right thing to do. It's a good thing to divide the coins of several groups in a portfolio and many have had success doing so. In common sense, what will we use when we need money suddenly if we put everything in there. At least there should be savings as an alternative when we need it.
Yeap, putting everything into crypto it's not an good choice as you said and maybe splitting it by buying some stocks and make an good portfolio, people need to manage their money wisely but divide it to long-term or short-term investing beside that savings money for urgent situation, We never know when we need money so it's good choice to put some money on savings especially on bank, Beside that gold it's another good choice since it can easily to convert on any place.
