When people talks about diversity in crypto space they only point at big projects and small projects combined but no one ever talk about their life savings, I've seen people putting all they have into crypto and yes they have more than 5 coins in their portfolio but is this the smartest move?
Personally I think the smartest move is to have some funds offline as well, if you know what diversity means then you should be smart enough bro know that nothing is guaranteed, have some money 💰💰 offline and some online (crypto and other), putting all your eggs in one basket is bad and too much of everything is also bad
If you have an idea what is financial management, then I guess you'll never have to worry about the money that gets in to investments and the money intended for life/emergency savings including insurances.
Diversification of asset doesn't only mean you focus on different types of crypto, but also with stocks, commodity, securities, and others.
It is always a smart move to diversify your investment IF you know what you're invested into.
The most common mistake of investors, is putting their money into something they lack of knowledge to.
