The surge is due to the upcoming fork to BTC Gold. The community learned at the last fork that you end up with a mirror coin. I.e If you were holding one BTC then you were holding one BTC and one BTC Cash post fork. Same goes for this one. I'm running a contest to win Bitcoin to celebrate the recent surge if you want to have a go at winning some give it a gander. Cool write up and will up vote and follow. Steem on. :)
