So, the main question is that Is it risky to invest in new crypto coins/tokens? or it is good for a very certain time of investment?
Actually investing in new coins is very risky, and this has been my personal experience. I bought a newly launched coin, and the price increased rapidly. But not until 1 day the price drop exceeds the price I bought. Of course when we hold back, it takes a long time. New coins cannot predict how far the price will hold, sometimes rising too high, sometimes dropping very drastically.
