In general, you shouldn't store cryptos on exchanges - get an offline wallet or cold storage. While nothing is for sure yet about the forks, it's looking like the UASF will happen August 1 and the UAHF a few months later. Maybe. Regardless, the safest thing to do is pull your BTC off until things get resolved. There's a lot of FUD running amok and we are seeing a lot of volatility again.
