The bull market is back, definitely. Both bitcoin and ethereum have gained over 25% in value from January to date. Heck, the entire cryptocurrency market added over a $80 billion within the last 120 days. Tell me, what is that if not a bullish market, huh? 
Not yet, I think. When bulls come, the growth of the cryptocurrency will be sufficient. Bitcoin and some altcoins gained, but it is not yet enough. The real bull market can start later.
