For those OG's or early adopters with Bitcoin had sold off their coins on cheap prices does have that huge regret into the decisions that they had made out but we cant be able to totally blame them out since no one had trusted up Bitcoin into those early years on which even trusting to buy or bid up on $100 for 10k Bitcoin will really be that still give out that kind of doubt. Yes, we can say that it is really just that a waste since he didnt hold long enough but we cant totally blame them out because there's no such thing about guaranteed future. It is really just that we can say just because we are on such condition or situation where the price of Bitcoin had hit or reached up $100k. Imagine on how much he had made out if he had been able to hold for 15 years. Well, regret is always at the end and being diamond hands is never been easy even if you are really just that simply holding your coins. There's no assurance that you can be able to make money on lies ahead and we do always secure out profits as much as we could whenever we do see the opportunity. We do know that mining Bitcoin into those years or days arent that hard, this is why they arent thinking about holding and making instant profits as the money that they do able to obtain money for some assurance.

15 years ago only a few people understood bitcoin and at that time it was probably considered a useless coin... because over time until now it has become a fantastic value, it is quite crazy if someone is still holding it today.

If he still realizes maybe he will still have a long history in bitcoin.

Currently bitcoin is still around $100K if you look at the next 15 years maybe the price will be millions of dollars again, it's just that you can't compare bitcoin in early 2010 which was worthless until now it must be different.

In the past, very few people knew about the importance of Bitcoin, and those who did have become billionaires in the present day. Those who kept it in their wallets instead of selling it are now making incredible profits. The person who placed an order to sell $50 worth of Bitcoin and then canceled the sale has now become the owner of a billion dollars.

I don't think those who were hodling from that point in time didn't sell at least a portion of their investment (or even most of it) going to the 100k mark.
However, if they didn't - that's a crystal clear power of will and belief. Real hodlers to the bone.

Even if all of those who were lucky enough to own alot of bitcoin in the early days happen to have sold all their bitcoin at a givweaway prices, though it's and was a stupid thing to do, but we really can not blame them, and neither should they blame themselves, for just as you have said, no body can tell the future, and bitcoin being the very first of its kind, non of this people were able to decern what its future could be like, no one was able to tell if it will succeed like it has today, or if it will be a flop like several other internet money before it, I believe that  if all of this people knew how successful bitcoin would be today back then, non of them would have sold a single bitcoin, or they can only sell a few to sort out issues and continue to hold the rest even up until this moment.

It's the same thing today as well, alot of people today are selling bitcoin, and no one can tell what it's price will be in the coming 15 years from today.

You're right how can One compare the value of bitcoin as at the early stage when the  price is still very much affordable with now that the price of bitcoin has gone this far.  We don't have to blame anyone who sold his/her bitcoin back then, of course not everyone that is aware that bitcoin has a good potential in the future, if we keep blaming them for selling their bitcoin back then I think this will make them feel depressed why most people can also decide to overlook. Because most of those early investors that sold their bitcoin back then I'm pretty sure they sold it for a reason best known to them. It might be that it has gotten to thier target this is why they have decided to sell, is just a matter of choice.

I think this post teaches us a very important lesson. I know all of us probably have missed accumulating Bitcoins during its initial phase. So we all need to ensure that we do it now so that we don't regret about it after another 10-15 years. Because Bitcoin has every potential to break it's own record multiple times over a period of time.

So go ahead and start accumulating from today if not started already. This is going to become the driver of the world economy one day.

This was probably discussed sometime in 2020 when Bitcoin hit $68k and everyone was angry at the person but same Bitcoin went down to $15k years later, instead of buying the amount they can afford, they didn't and say it will die but today it's trading at $100k and everyone is yea, he messed up and he might be regretting later. This is how we are going to be here discussing the same topic in 30 years in the future when Bitcoin will be trading for $1m+

Everyday that we see Bitcoin cheaper, it presents a buy opportunity for everyone, the price can't stay like this forever. That person that auction the Bitcoin probably brought or mine it and needed the money. If today he knew Bitcoin will be this expensive, he will never sell a single one of the but probably there wasn't alternative for him which is why he auction everything, people definitely do things for reasons, we can't judge him because we don't know why he offer them at that amount.

If only these individuals with the buying power and opportunity had a blink into the future of our today to have known that, it was a life changing offer in no distant time as I think, 15years isn’t a lot of time given how far Bitcoin have come in those years, such investor would have been granting interviews by now.

The funny truth is, we might be making the same exact mistake right now. By not having to buy at the price we have it in today, it might be a regrettable choice in 5 or 10years.

Actually, if we look back, we can say that we're already too late. Those who've just joined the community today can't get the perks and privileges that were accorded to the early birds. But there's no point regretting, crying over spilled milk. Whether we like it or not, we can only accept it.

Let's just content ourselves with x2, x3, x5 growth from here that might take years. It can't anymore be x3 within a week or x10 within a year.

Those who came early and hodled strong through the years are rightfully rewarded. Those who came late are fairly rewarded as well. Those who were waiting for the $10,000, $30,000, $50,000 that never came will get what they also deserve.
