I think it is necessary to say that I became rich thanks to cryptocurrencies. And above all first of all I mean Ethereum. It is a very interesting cryptocurrency which has good prospects to grow further. I am sure that it will be so.
But Ethereum now is too big. It can't give x100 anymore. Even x10 looks like a dream. But anyway there are enough projects that could give such profit in future
But the chance to lose money is also higher, it is necessary to keep part of the funds in the fundamental coins as they are unlikely to fall and not to rise , and the fundamental ones can back up your finances and wash away in case of drawdown will restore your portfolio
