Why does coins prices fluctuate so much and it is never been constant making predicting price much harder and much riskier and holding on to coins can be the best way right now.
why does it change prices constantly and never stagnant?
A lot of small cap coins don't really change, they just appear to on the dollar price charts. If its main trading pair is BTC or ETH, then it just needs BTC or ETH to change dollar price, and then the small coin will also change by the same amount even without any volume - if it's worth 0.1 ETH with ETH at $200, then it's worth $20... and if ETH then goes to $300, then with no trading the small coin is still 0.1 ETH, so it has gone up to $30.
