Because we don't know the future of cryptocurrency. Would it be good like 2017 when bitcoin price rising so high with only 2 months, or it would be bad, you know what is the bad thing. It's not like when you investing on gold. You know the future because gold price annually rising. So when talking Investment, gold is the best. But when talking trading, my opinion is cryptocurrency is the best
Yes, you are right, we are affraid, because of non stability of all prices and of sittuation in general, so we can not know for sure, will this market survive, or will it fall.
Some people do not have the idea and knowledge about the crypto market and that is why they are unable to know about the benefits of crypto market and live with just a perception which has left by the Bitcoin long ago. Get out from the perception of feeling fear in the market as we are entered into the modern world and all we need is to handle our processes.
