Yes, the biggest problem in the market is the same. The market's decline in all cryptocurrencies has fallen, and almost all the coins in the market will rise. No single coin can rise alone and is not controlled by the market.
The biggest problem I see so far in crypto is only the market price, we don't know when will it rise up and when will it fall. Our investment rely on the growing price in the market and if the price is down we are all in dip situation.
