it's not supposed to be debated cause we've all seen the success of the project from the first day of creation by Satoshi to this present day
Now I'm curious, do you hold Bitcoin since May 2017 till now? you registered on that time and you're believing in Bitcoin since the first day of creation, which mean there's no way you will not buy Bitcoin if you believe it in the first place.
I wonder how many of those who invested early on actually managed to hold long enough. I joined only around 2015, and even I remember a time when $600 per BTC felt like such a great price. Apart from selling, it was easy to lose coins due to scams, locking yourself out of your wallet, or accidentally making transfer mistakes.
But no matter when someone invested, surely it was hard not to sell at some point. In the grand scheme of things, I agree it's not too late to invest, but people should do what feels right to them.
Yeah, it was not that bad if someone sell their coins especially in 2017-2018 because it was the time where Bitcoin price rise so high and no one expect it. They not want to end up like Tulip Mania, they might think in 2018 it's over, but since Bitcoin can make new ATH in 2021 and 2024, it's no longer Tulip Mania.
