I don't wanna be a pessimist, but at the current time I do not believe bitcoin will increase a hell of a lot more. It will top around 20k dollar, atleast that's my best guess right now, mainly due to the high fees that are needed, making the coin useless if you only got a small amount, it shaves off a big chunk.

If anything, I see certain altcoins rise up more, as they have faster transactions.
