I've been thinking a lot about this issue. I heard more than once that many are discussing this topic. Is it safe to invest everything in one, two cryptocurrencies? Or to distribute all the money in all the coins available for this amount?
Its NOT SAFE to put all your money in cryptocurrencies itself. I am not just talking about 1 or 2 cryptocurrencies but I am talking about the entire crypto space.
The basic fundamental of financial investments says diversification, never put all your money in one financial instrument, diversify it. If you believe in crypto more, put a bigger part of your investment in crypto, but never go all IN.
Alongside crypto, invest in real estate, gold, bonds, stocks and where you can. This eventually safeguards you from uncertainity and complete fall.
I am not writing this because I am against crypto, I even have 40% of my investment funds in crypto myself, but again, you can never be certain in only 1 financial instrument.
