Diversifying your funds into financial markets other than crypto is of course highly recommended, if it is in accordance with finance. But in this crypto room the majority of people invest their funds in bitcoin and altcoins.
I personally currently still allocate my funds in altcoins and wait for ROI, so that I can allocate my funds to real state.
It takes a balance between financial markets and investments in the crypto world, this must be balanced if we make these investments, the financial markets are not too risky that we will face, in contrast to the cryptocurrency world which has big risks, if we can't control them properly and well.
Altcoins are not so risky in investing, but if we invest here it takes a very long time to provide maximum profits, even if there are fast ones it will not be so maximal and promising, so investing in the crypto world requires proper analysis.
