I don't know if this is for real but what he said about 2017 that bitcoin will reach $10,000 happened and went through another all time high at close $20,000 and starting to move backwards and slowly at this rate. Let's wait if 2019 bitcoin will be at $100k. He's not the only one that claims to be a time traveler, I'm much interested with bitcoin/crypto related "time travelers" that are giving optimism to the investors.  

Next time, we'll see someone claims to be one of it and tells that aliens are also investing to crypto.
