I don't see any reason why wheelz1200 will not be happy for buying aggressively earlier before this dip like you said. He has already used that opportunity to increase his bitcoin portfolio higher and that's what is the most important thing for every investor. For them to take advantage of the opportunity they have to invest aggressively when they can for a good increase in their bitcoin stash.
You are sounding like a trader for you to say that wheelz1200 will be regretting when he is accumulating bitcoin for a long time without selling a dime. DCA method doesn't prevent or stop any investor not to buy aggressively when he can irrespective of the price of bitcoin. As a matter of fact, mixing the three methods in a proper way and buying aggressively will give you a better result than only DCA in the long run.
It's not the price that you bought your bitcoin is what matters, what matters most is for you to be increasing your bitcoin stash in a speedy way with your discretionary income and don't over aggressively invest.
Don't be in a hurry to include that I sound like a trade because I have my reason for the statement I made about wheelz1200 in my post. If you go back and read wheelz1200's post very carefully, you will understand that his intention was to aggressively accumulate bitcoin since bitcoin has been hovering around 90k plus for a while, and he plans to sell the bitcoin around September/October when he thinks bitcoin will set a new ATH, which will even make him look like a trader because he will be selling the bitcoin he accumulates aggressively in the coming few months. For someone who has such intentions, do you think the person will be happy after accumulating bitcoin with the intention to sell his bitcoin for short-term profit, and instead of bitcoin increasing in price, an unexpected dip happens immediately after the person just accumulates bitcoin?
Supporting such an idea of buying now with the intention of selling around September/October may be the reason to refer to you as sounding like a trader and as a matter of fact, that is what it is and such ideas should never be supported in a topic where we are discussing how to build a long term portfolio of several years. Buying and hoping to sell in seven months time is short term investment which should be avoided because it can end very badly. We are familiar with the fact that Bitcoin price is not always accurately predictable so setting a time when you want Bitcoin to reach all time high will likely lead to making wrong decisions that may end in regrets or loss of money especially when the investor more than his discretionary income.
It is good and more peaceful to think long term even beyond this year/market cycle as this will make the investor put only money that he can hold in Bitcoin for a long duration instead of a few month. Realizing this, I adopted the DCA method which I will be doing continuously for many years without selling a single Bitcoin.
