Honestly, with the ratio of block reward and bitcoin adoption, there will be an exponential growth of bitcoin price if we do not consider the resistance which is competition, scalability issue and government regulations. But disregarding these resistance, there is a possibility that Bitcoin can probably reach a million dollar per coins as what of one of the article stated but it won't be happening on 5 or 10 years. Though I am convinced that when all all the coin is mined and bitcoin is still the leading cryptocurrency, it may be worth more than $100k dollar a piece.
I am not seeing few of these resistances to persist for at least next 6 months. Bitcoin has pure dominance among cryprocurrencies hence there will be no obvious competitions and recently devs are coming with segwit2x, if it is not a fit one, surely they will come again segwit3x or anything similar to that, so scalabilty is no more a stopping. Finally government regulation may give short term impacts but definitely long term impacts as bitcoin can survive without any external help.
So, literally we do not have any resistance to prevent us from having exponential growth. Those capped and scheduled supply against rapid growing of adoption will surely lead to exponential growth.
With exponential growth of prices, we can expect bitcoin prices to reach a stage where one satoshi may have value like one dollar or even 10 dollars. These are all possible probably in next 10 years itself given that there will be no big bad news in and around bitcoin ecosystem.
