because from my understanding and experience in bitcoin, theirs no time you purchase bitcoin for investment is not best time, except that your motive of investing in bitcoin is for short term,
Really? Was buying at the ath of $68k the "best" time as well?
I get it, we are on the Bitcoin forum and (almost) everyone is pro-bitcoin, but let's not get detached from reality. Buying in at something that looks like a potential peak is not a smart move even if you're here for the long run. There's no guarantee that ath will keep getting higher every cycle or that cycles will keep repeating themselves as they did in the past. That's impossible.
The ultimate goal when investing in bitcoin is profit, when and at what price is extremely important, so I also disagree with saying that there is no best time to buy. If we bought bitcoin for $69k last year, we most likely won't lose money when the next bull season comes, but we won't be profitable either, and that's a real waste of time and money. As for me, I'm still accumulating bitcoins, but when the price crosses $50k or nears the old ATH, I'll stop buying and wait instead of buying regardless because the future is unpredictable, including bitcoins.
