Actually didn't Bitcoin hit 20,000 in 2017? If he really was from the future he would have taken this into account. Also right now the price of Bitcoin is $8,200. Even if it becomes a bull market....12x would be unheard of. The moment Bitcoin hits $20,000 again you know governments will put their foot down. BUT if it does hit $100,000 then I will believe in time travel. HAHA
