I think one of the main reasons is the complexity of cryptocurrency processes for ordinary people, from which fear and frivolous attitude is generated, which is detrimental aspects.
I dont think that it has any problem with crypto at this moment. Fluctuation is its nature and yes i feel this is what cryto's strength unlike fiats. Crypto market's growth is just because of the fluctuation and demand to it attracting too many investors.
So it is very important to know crypto currency is all has the most fluctuating nature and miner rise fall does not matter, infect people wait for this opportunity so they can buy at low price, the problem is only lack of knowledge which makes people to sell at panic and it gives market a wrong direction, to dump, fluctuation is not the problem for sure.
