Sometimes based on personal circumstances, cash flow circumstances or just getting caught up in the BTC (FOMO) hype, people will end up investing more into BTC (in kind of lump sum ways) at certain times, so there could be cases in which a person invested way more into BTC at the top of BTC prices in 2021, so then that person may well end up still being in the negative because they are having to make up for their having had front loaded their BTC investment at times that ended up being higher prices than they are currently.   Those kinds of mistakes do sometimes end up happening, and maybe some of those kinds of persons might end up DCA investing into bitcoin 3-4 years (or even more) before they finally start getting into profits.  Of course, no matter what there are not any guarantees that your BTC portfolio will end up in profits, even though many of us have certain levels of confidence that bitcoin is amongst the best of investments currently available, if not the best investment, and because of our assessment of bitcoin, we continue to buy into it, even if it might take a while for our holdings to get into profits (an might not ever get into profits if something ends up negativing bitcoin's positive investment thesis).
