you are right, the 90% bitcoin already mined, so there are only 10% bitcoinin the world that can be mined, you need to know that the diff increasing. so 10% will be fully mined in a very long time, and if its already mined 100%, i think the price of bitcoin will increase, because the demand will be higher than the supply. am i right?
That's not going to be happening in our lifetime so I don't see how we should celebrate it, maybe our children will be able to enjoy that and hopefully they will be able to appreciate bitcoin. I think that when the continuous increase in the population and with more people learning about cryptocurrencies, the possibility of growth is limitless, it's just a matter of demand.
