For this time anything can happen. but I think that the world will switch to another payment system, the world financial revolution will take place 
Can we just think of closest years? 2025 is a long road before we can reached there.
Honestly I don't mind that bitcoin price isn't much that higher compare to what we are today. As long as bitcoin gained continously it's momentum, then that's what Im eyeing more. Rather to sees only around $8,000 on bitcoin price once 2025 came than to see bitcoin will have such lowered price of what it is today on that year.
Indeed, to have a prediction with a relatively long period of time is certainly not an easy thing, especially for bitcoin because there is no definitive prediction about bitcoin, and all possibilities can occur in bitcoin, but of course we expect a positive possibility to happen in bitcoin for this year.
Well if john mcafee still has his d*ck intact at that time, then bitcoin would probably be worth millions already. Though i'm not really confident making such predictions as i don't have as many btcs as the guy but i hope he keeps it on
