If you own 1 BTC and you sell today, someone holding only 0.1 BTC will be much richer than you in the coming years.
Yeah I agree that hodling Bitcoin could make you rich in the next few years, but that doesn't mean If someone sold their 1 Btc today, the person who holds 0.1 Btc will be much richer than the other.
Let's say, that person who sold his 1 Btc today just put up a business and then It became successful in a year or two. Don't you think the ones still holding 0.1 Btc is much richer than the other?
However, those who wants to enter the crypto space won't be that late for the current price. Bitcoin just calmed after the $60,000+ ATH surge, and It has yet to touch the 6 digit figure.
you have actually valid point on that, for someone who will sell his btc today and invest it on his business and hit it off. that's one scenario to look at this situation. but if the seller just use it to unimportant things, then, that's a loss.
whatever you decide for today, whether you hold or sell, make sure that you have other plans to make this action valuable to you.
as no one can give you what will happen in the future, it is for you how to strategise things in order to take advantage of the opportunity that you have right now, knowing the capability of bitcoin in the market.
