While I agree that lots of people are scared to invest in crypto, I know some things could be responsible for this.
Scalability us a big issue with cryptocurrencies and it's difficult for most projects to scale up to a large extent.
Another major issue is value. The value fluctuate and the ups and downs become do difficult for some to comprehend.
Those peoples who are scared are the ones who are not into profits that deep. There always is risk which needs to be taken in the field of cryptocurrencies in order to make profits. If you do not have the guts to take the risk then how could you expect the profits to be big. Those peoples who now are trusting into cryptocurrencies are the one's who are investing most of their capital into bitcoins or any coin.
The value for bitcoins is not actually a negative side to be considered but it gives opportunities for a lot of traders, holders to make instant profits by keeping constant buy/sell orders.
