Bitcoin will never be hopeless. But we shouldn't splurge ALL our money on bitcoin (just my opinion). BTC is still 6k+ USD. Compared to it's 4k USD from september and it almost reached 20k USD on December. Who could have imagine that in the last quarter of 2017 will be like that .
As what i have noticed and learned here in this economy. There are accurate predictions to when it will rise and fall, and besides who would have actually thought that it will rise that high according to what you have stated so, but look at it right now, it seems that it goes down for a bit as a major pullback like what we often see on its market every year. So in short, there is no point in losing hope, when you are investing and at the same time savoring its benefits right?
