Sell it as soon as you see price 10% higher than your entry price because I think it won't have a future ahead of it. Unlike BCH it's development is not well planned and it is a makeshift fork that didn't really contributed a good new feature to fork version. Still, it got potential to grow up more so hold it tight for now. It would be a waste to not get some profit from your money, it would be a waste to sell instantly.
