In my own opinion, it makes no sense trading your Bitcoin for minimal gains, because constant tempering with your stash of Bitcoin might compel you to sell thinking that you can get it back at a lower price which might never be possible again.
Ok let take a look at those that sold their Bitcoin at $69k thinking that they can later buy back, now Bitcoin has gone up to $100k, do you think that Bitcoin will ever collapse to such level? No in my own opinion, so selling and buying back is not the ideal approach that can be used to build a generational wealth because you may miss the big spike in price if you don't have any significant stash at that moment that it happens, so selling and buying back is not ideal too me.
Definitely not, I don’t think those who sold at that price would be able to buy back now and I don’t think Bitcoin would be dropping to that extent $69k anytime soon or ever. It’s a matter of making peace with what price it is now and push yourself through buying at the existing price and have plans on how to manage it.
The idea to sell and buy back complies with the buy low and sell high principle. It’s kind of hard to see that principle as useless or not to make sense. I take it for a strategy risk that individual traders or investors put themselves through. Perhaps not the best strategy given the unpredictable nature of Bitcoin but, it’s a strategy nonetheless.
