Now only the market starts to increase, now it is in green. But we don't know whether this will continue or not, at the same time 2019 will be good for cryptocurrency. The price bitcoin will increase for that we have to wait with patience. Now buy the bitcoin at low price and hold it for future.
The pump still hasn't happened, the green of the market this time doesn't mean a pump but it's just the usual fluctuations. No one knows for sure when the pump will actually occur, buying when the price is low is indeed highly recommended if you do have high confidence to hold it. The purchases you make do not just follow people around, because this involves money and profits and you should do it carefully and full of research so that you do not panic when prices fall even lower.
