Procrastination is a goal killer and a dream killer as such every investor that wants to go far in Bitcoin Investment should not entertain this act if not it will ruined your plans and deter you from achieving your aim as an intending and existing investors.
You said something about perfect time to invest, I think there is no perfect time to invest in Bitcoin although the dip season is said to be the best period to invest,
But there WAS a perfect time to invest in Bitcoin. That was during the bear market when the price dropped near/under the 200-Weekly SMA. Because people miss it doesn't actually mean that it doesn't exist.
¯\_(ツ)_/¯
That simple "line" holds historical significance in Bitcoin, although "some people" may disagree.
what if the price of Bitcoin keep soaring, are we going to still be waiting for the price to drop before we invest? What if in the process we spend the fund while waiting for the dip time to come? I think this are discouragement mindset and I see them as procrastination that tends to divert our attention from from doing what we ought to do whenever we are ready.
I believe you're applying the wrong attitude towards choosing a DCA strategy. A DCA investor accepts the condition that he/she can't predict the market, and therefore purchases an asset in a fixed amount/in regular intervals. Telling yourself, "what if the price of Bitcoin keep soaring", will merely lead you to FOMO.
