Fall of the market may be a profitable time to buy cryptocurrency but it is very risky time to buy cryptocurrency.
It is very important to check all the projects before investing because not all the projects will survive during the fall of the market.
A lot depends how many people use the project and how useful it will be in the future.
Instead of being confused by the risks and the many projects that you have to look at and you research to find out what the future potential is from now on. You are better off directly choosing coins from well-known projects like Bitcoin and Ethereum because they are still in the top position right now and obviously there won't be much loss that will happen to you even though the potential profit won't be much immediate.
