Actually, it isn't. It's about the whole crypto market. A lot of money was sucked out of the circulation during past month. Some of it comes back, but the majority in BTC. Once BTC is self-regulated, money will flow back to alts. The worst thing to do now is to sell. "Lots of newcomers are giving their money to veterans.
This market is so dependent on BTC that it's kinda sad. If Bitcoin is correcting, everything else is too. My opinion, Bitcoin has started a fresh set of 5 waves up and we are currently seeing wave 2 (down) of that 5 waves. It makes people wary that we are still in a correction. Once it starts wave 3 up the market should see some strong moves up. If you look at the crypto market capitalization its the same thing. Wave 2 will probably correct 50ish percent of its last increase.
