There were worst days for crypto. BTC dominate the market and alt coins cannot do anything alone at current market conditions.
After long bear market we saw some green days after Q1 to end of Q2..
And last 2-3 months we are living in a bloody market. By the way red market give good opportunities for traders. And also good opportunities for investors who focus on top ranked coins.
You were right, the worst days for crypto were when bitcoin rose rapidly in dominance and took away all capital to maintain the value of altcoins, many altcoins have lost their true value, more precisely, bitcoin has helped those altcoins fall into a hopeless past and have no chance of returning. And whether we like it or not, we also overcome the worst case scenario so we can move on in the crypto world, blood can appear a lot, but green will still appear, based on our knowledge to make money from those bloody things, recover from the bad days.
