So if that is the case , I don't see a world were bitcoin would be mass adopted
Firstly , bitcoin is limited in number (21 million) and the world population is higher than that if not twice , so it can't be mass adopted.
It is indeed capped in 21 million BTC but it is divisible into satoshi. That way it virtually nullifies the concept of scarcity since people can have a fraction of it.
eg:
if you invested in bitcoin at an early stage it would have made you twice richer especially in countries where there fiat price is lower than USD. Like Nigeria($32k in naira is over 15M) .
Bitcoin blockchain is free at the moment because everyone is holding theirs to see it next pump , imagine a point where everyone wants to transact , it makes the blockchain accumulated , high miners fees, and imagine paying for a good with bitcoin and the seller has to wait for hours or days to receive his payment.
We could say bitcoin is a great investment but i can't see it as a currency for the future .
Please it is from my own point of view
I don't believe that bitcoin is created to eradicate poverty even in some level of it because its access from the beginning until now is kinda limited to those who have internet, gadgets, and devices. I think it is some way of disagreeing against the central institution especially the financial institution where they just create money out of thin air that causes inflation and devaluation of fiat.
