I would not sell it tbh. In fact, I'd buy as much as I could unless the reason it dropped so low makes another price pump highly unlikely.
It has changed many people's lives indeed. And, now we are accustomed to the price being this high but we shouldn't forget from what level Bitcoin has come to these days. It also means that we can see much higher levels in the future that we will be very surprised to see again. And there will also be new people whose lives will change in a very good way again.
This applies only if things don't turn upside down, which I personally do not see as an impossibility since Bitcoin has not had a drastic price correction like it had back in 2015. The trend could change at any time in a way it's never changed before. Perhaps it'd be impossible for this trend to only keep comtinuing.
But this is what speculation is.
