In my own view and opinion altcoins is important part of crypto currency I didn't believe their price diwn to zero, is useless if bitcoin uprise tehir price at 100$ in the market but we can't trade it into the other coins or tokens. So much better bitcoin stay at price at 20k usd than to reach 100$ usd but its not worth it to trade into other altcoins. Do not offend if that happen come its all useless.
