It was actually in the 40's at that time. And that is irregardless of my point considering that just about all of the Top 300 coins saw a similar move. That move had nothing to do with ICOs. It had to do with billions coming out of bitcoin and looking for a home, and that home was the Top 300 altcoins. Nothing more, nothing less.
Will that same type of action happen again?
Who knows, but I don't doubt that if bitcoin makes new highs and starts to correct or go sideways money will pour into altcoins again. Not sure if it will be all of the Top 300 again, but there is a good chance it pours into a lot of them.
