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.
There will always be changes at any time, the market situation will always change and we cannot determine whether it can end or not. It is true that during the beginning of 2019 we have experienced a number of fairly good increases, and even experienced a decline in some time. The market will always change and is largely influenced by demand factors. Prices will never stop to change and we must be able to take advantage of every change that exists.
