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.
Another thing is that Bitcoin is always more expensive than altcoins, and this is always a case where newbie traders enter the crypto world and buy altcoins thinking that Bitcoin is too expensive. They have the mindset that since the altcoins' prices are lower, investments in them will be more profitable.
Time has taught us that those who have invested in Bitcoin
BTC are more profitable in the long term and short term and those who were holding bags of altcoins are only regretting it.
