By looking at this chart presented here shows that Bitcoin sentiment is bullish, by looking at this last bullish engulfing candle sticks, it shows that their are a lot of buyers in the market, so who are those folks that are saying that it's too expensive to be buying now?
Those buyers in the market do they think they don't know what they are doing?
It's only myopic people that will be seeing it that way as expensive because Bitcoin is seriously on the rise, and I see it setting a new all time high in the nearest future, that's why their should be no wasting time for those that hasn't started accumulating it yet, the better they seize this opportunity or regret later.
