Yes, when talking about a market going up, the sooner the better, but here I don't see any consideration when the price goes down, keep in mind that not only can opportunities go up at any time, but opportunities to go down can also occur at any time. Here talking about altcoins, when talking about bitcoin maybe I will be very optimistic.

Doing frequent analysis in my opinion is a good thing, as long as it is accompanied by buying (not not buying). However it is something important that must be done, otherwise it might be said as a rash act, for not thinking carefully before we buy.
