There is going to be a hardfork as BCC coin is coming but that is just an added bonus. Do not sell your Bitcoin cheap and panic and if you have more funds, when or IF it dumps a little, buy some more and you will be the ultimate winner. I hope also BCC sells for very cheap so I can buy a few of those as well and hold.
Smart suggestion indeed! It’s really sagacious to hold onto your bitcoins even when the market is facing downfall. As you have said, there is absolutely no need of selling all bitcoins on August 1st. even if the prices pump beyond expectations, keep some coins in your wallet. Good luck for Segwit.
