No doubt, Bitcoin has huge future potential but there is a big obstacle in this way, 'Scalability'. People argue that Bitcoin can be fragmented upto 100 millions units and if large number of people adopt Bitcoin there won't be any problem as people would start using Satoshis. But is that possible? Absolutely not! Scalability issue has limited Bitcoin diversification to the maximum of 4 decimal points. If we send lower than that, fees will supersede amount and transaction will become unfeasible to conduct.
So, we shouldn't expect anything above $100K for Bitcoin if current version i.e. Bitcoin Core continues to dominate Bitcoin in coming years. On the same side, I don't advocate fork or flippening rather there should be some consensus among miners to solve scalability issue.
