Regrets won't matter much because in the end we still have to move on. What I mean is that although we are allowed to regret something, in the end we have to move on because if we only lament what has happened then we will only be trapped with memories of the past that never end, which also does not make us grow.
I understand we must feel the same way where the thought of “why not buy bitcoin long ago” is always there but in the end things like this cannot be changed and it would be better to focus on the future than just having to focus on the past that will never be repeated.
We can still buy bitcoin even though it's not what it used to be but in the end if there is seriousness about wanting to own bitcoin or invest for the long term in bitcoin everything can still be realized because it's never too late, there's no word buying now is too expensive to buy if the focus is for the future then we can do it from today without regretting the past.
When there’s a will, there’s a way. So no matter how expensive it is at the moment, if you really have the real intention to buy, you will find ways to buy. There’s never too late to invest as long as you have the eagerness deep inside. But on the other hand, even if the price is still very cheap, but you don’t trust it anyway, then you will certainly make an alibi not to buy, simply as that.
Regrets are normal, as long as you don’t tolerate yourself repeating the same mistake again.
