Now is really the best time to buy Bitcoin everyone knows that and not to act just because the Man you mentioned above has advice people to buy Bitcoin and thank him later. The problem with investment in Bitcoin is that, it is possible that if one buy now and it happens that there was a further decline which may take a long time for you to be in profit and the patience to wait till your investment turn profit is the major challenge.
if we will look at the big picture here, i can say that this is indeed a good time to buy. we have war ongoing between russia and ukraine, and it is only a matter of time before people realise that btc is a very good alternative to send money anywhere in the world especially those people residing in the affected areas.
we don't need a billionaire to realise this very good opportunity. so while btc is still in the 30s, make sure to act what is needed to get your profits later on.
