If we see the history of Bitcoin, then it's pretty easy to see how Bitcoin recovered its price. It would take time to recover, but eventually it did. So at the end of the day, holders don't need to be regretful. I am talking about Bitcoin, not about any other altcoin. Because even though the Bitcoin price has recovered, many altcoins haven't recovered yet. Even those who bought Bitcoin at the top in the last bull run, I believe they are almost recovered. If they are still holding, they will be in profit within a couple of months. Bitcoin has given us a costly lesson that holders won't regret. We should take that lesson and keep it in mind for the future.
Yet people don't seem to understand or accept that reality , they kept having second thoughts about investing in bitcoin calling it as scam when there are almost 15 years now of bitcoin existence and have served thousands if not millions of people (though there are some failure of course) .
maybe once bitcoin reached 1 million dollar per bitcoin then those are the days that they will regret those words of them.
