Just like you, I also miss those opportunity to buy when the price was significantly low not because there was no funds but because of the lack of knowledge towards bitcoin or should I say I had a wrong perception of bitcoin, but its was not until the massive growth and awareness of bitcoin in NIGERIA and my locality to be specific that really got me curious toward the trend that is bitcoin and thanks to my curiousity, I have learnt a lot as from the time I was guided to this wonderful forum. But am still not all that regretful though because of the fact that the price still went low to 16k last year after hitting its ATH in 2021 and I was lead to know and understand that instead of whining I should rather see it as a second chance and a golden oppurtinity to buy btc during last year dip and do what most successful crypto investors do which is to HODL till the prices goes up and significant enough to sell.
The many opportunities that exist are sometimes often wasted because they are too worried about the fud circulating out there. Some of them have great belief and that is the characteristic of those who are successful in the end. Indeed we have seen a in the movement of btc when it reached $ 69k and a year after ATH BTC fell to a price of $16k now on such occasions there are still some people who have weak hands selling at $16k and if we look at this price even we compare of course BTC has turned things around from $16k up to a price of $28k as of today and its just lucky for those who HOLD.
My conclusion is that maybe it's never too late to buy BTC even though we will buy in small amounts but if it is done regularly every week then we will also have the hope of getting big profits when Big Pumps come or when new ATH is reached.
