It's down again at $7,300 and this made every single trader to be confident with the alt coins. They jumped already and pumped some popular alt coins out there, too bad that I was into a nap a while ago and did missed the chance of buying some bleeding alts. Anyway this is just a very few reason why bitcoin is up before because of the cancelled fork but know there's no more worries of taking over the network and choice on what chain to support. This bring up everyone's confidence to buy some more bitcoin.
