When the price of BTC rises sharply, most altcoins will dump. When the price of BTC drops sharply, most altcoins will dump. The altcoin market requires just the right conditions: sideways congestion or prolonged grinding top in BTC/fiat price action.
At some point, people need to come to terms with the fact that alts/tokens were in a bubble in the first half of the year. It takes time for the market to bottom out and for the weak hands to get shaken out.
I'll say one thing. I'm still mostly holding only BTC. But I have started accumulating a few altcoins... slowly scaling in. And I'm certainly not dumping anything I've bought in this range, no matter what happens now. Sell after 95% drop from the top? No thanks!
