$5000 The highest is the maximum price that will be achieved bitcoin in my opinion, it could be more when the future of all people in the world using bitcoin.
All people in the world to use Bitcoin? Nah, that's unrealistic and will definitely not happen. I think we may be happy if we at some point manage to get 5% of the world population to adopt Bitcoin. 5% of +7 billion = at least 350 million people.
If 350 million people use the bitcoin regularly, the price will be over several hundred thousand dollar each bitcoin.
If bitcoin spreads worldwide and majority people use it the price may be $10k, but for worldwide acceptance of bitcoin it needs some decades.
No that's would never happen we need to divide first from 350 million people for every category, child will not include,people who do not believe bitcoin even though they knew would bitcoin,etc after that we can made a prediction but surely the price never reach $10k.
