may have to set aside several types of coins so that when experiencing an increase can be covered and still get a profit. so I think maybe now it should be smarter and selective about a coin owned.
when you see bitcoin go down can you see altcoin go up? I'm sure that will also pull Altcoin down. if this decline continues it will be bad in the situation of altcoin and trading. some investors will wait for the best situation to buy, but it will move very slowly. we experience it 2018 even now.
