Many people say that it will rise in price, as the supply will drop sharply. However, I believe that on the contrary, then people switch to altcoyins, which already surpass bitcoin in both the level of confidentiality and payment for transactions.
Supply drop sharply? New supply will be nonexistent from that point! The price will reflect that event years before it will even happen. If you think that Bitcoin will remain as it is right now for ever, then you are even more stupid than you portray yourself to be. In more recent terms, lightning network will offer people the cheap and instant settling transactions that they are desperately waiting for -- another important point you blatantly ignore. I however don't know if Bitcoin will ever be able to offer privacy centric features, which for me isn't necessary at all. I am more than fine using a mixer when I need it, which is what I have been doing already for years now. If people so badly want a coin with that's privacy centric by default, feel free to switch to Monero....
