Now is not a good season for altcoins. So I think, the cause of the market conditions is because interest in coins has decreased and there are many prices for the games played. If I'm wrong, because I still lack knowledge about crypto.
You could say since the beginning of 2018 slowly the price of coins began to decline when compared to the end of 2017 and slowly new projects turned into scams and many people were disadvantaged because of this. And for me personally, for the time being it is better for us to focus on how we can survive in the cryptocurrency market and at least avoid avoiding losses from the investments we make.
