according to my predictions, supposedly in 2020 bitcoin prices continue to rise above $800 at least. because next 4 years bitcoin users likely will continue to grow
Even bitcoin users will grow in the next 4 years, it won't affect much the price if all their thinking will be holding coins and will not use it regular services.
Anyways I see no much growth in bitcoin users in the next 4 years with high volume but surely it will increase the percentage as years will passed.
