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.
I agree with that, bitcoin has redress many times and has proven its capacity to recover to any price whenever you feel that the market has moved against you as an investor or holder, all that is needed is the patience to wait for some time before you see that Bitcoin has recovered and achieved your desired price.
This is the reason why I always tell those who think that they have missed out on anything as regards to Bitcoin and are feeling that they are already late to join the Bitcoin holders fold, because, bitcoin will always have a way to reward everyone who endeavours to be patience and wait for long term base instead of giving up at current point if the price of Bitcoin may not be to the advantage.
