Personally, I see it as a currency in terms of use of service and not just the part where it's valuable that it is being used on a day-to-day basis. It's not ideal now obviously but integrating it would be nice.
In terms of the end goal, I think it's never going to be enough now, especially seeing how valuable it really is now. It's just really amazing. I wouldn't sell unless I need to.
I also don't think any sane person would sell their saved bitcoins at this time when everyone is seeing how high the price of bitcoin is now and how much higher it can go. I regret that six months ago I sold some of my bitcoins, now I wish I hadn't sold them.
It is said that a man learns from his past mistakes, so I think no one should make this mistake now, if they have old bitcoins they bought when the market was very much down, they should save them for at least six months or a year from this point because we are yet to witness the actual bull run which generally occurs after the halving event in every Bitcoin cycle.
Don't be surprised there are still investors who have accumulated enough bitcoin that would choose to sell some portions of it to buy cars, houses, and other luxurious things. Do you think it is stupidity to do that? Think about it those investors that started investing in Bitcoin 10 years ago selling now and living the life they deserve won't be such a bad idea. In my opinion i feel like it is not a bad idea but selling their entire Bitcoin that is where they might be wrong.
