You are misunderstanding Mainblem because he never said that anyone should wait till bitcoin price gets to 100k before investing. He is only encouraging people to have a reason to invest in bitcoin whether the price gets to 100k or not this year.
cryptocurrency investment
It will be better if you learn how to use the word of bitcoin more often than using cryptocurrency so that you don't mislead newbies for them to feel that bitcoin and altcoins are the samw and have thw aame potential, because only bitcoin is worth investing in and not altcoins.
so what I know is that in cryptocurrency investment what you need to do is to watch the market before you invest
There is no way for one to watch the market before investing because he is a no coiner. A new investor should not bother about the price of bitcoin when he wants to get started since he already has the money to start immediately. He should start investing with DCA continously so that he can keep on accumulating his bitcoin bit by bit irrespective of the price of bitcoin because no one can predict the price movement of bitcoin, but he should only focus on growing and building his bitcoin portfolio for a long time.
