I think you should dump while it's high, seems like the trend won't hold so long, the price will fall down sharply because there are so many people want to dump the coin, you can try to save 20% for trading or investment ,we don't know how well the BitcoinCash will survive
Yeah the people who received BitcoinCash has been dumping the their free money so might as well dump half of my BCC holdings any buy myself a beer from the free money I got.
