Basically whoever bought it at 68k as well. The idea is true that price of bitcoin will go up, and people will keep on buying it, not everyone will buy a full bitcoin, and not everyone will be able to buy more than a few thousand satoshi at most, but the purchases will keep on going.

Considering the higher we go the less liquidity we have, we could say that most will hold it anyway, there is no reason to sell it so the buyers will be trying to get some of the few that is still standing. I can see how it could become a very scarce asset and the price will be impacted because of it. Maybe it will be 500k and maybe it looks a lot now, but when the day comes, you will see that it is going to be great eventually and could be done same.
