Cloud mining operations don't actually mine, they're ponzis so the fork won't affect you at all. Get out while you still can. If you don't want to believe me, just google "cloud mining scam / ponzi".
Let me know how that goes, or don't. I already know what you'll find.
Most of them are Ponzi and scams but if we do talk about genesis and hashflare they did really have miners and do actual mining which we can able to see their facilities but this kind of investment doesn't really guarantee to last long or would operate forever and for op regarding on his earnings it is indeed affected by mining difficulty which we know it does rise at the time goes by and genesis and those cloud mining doesn't really care at all on fork.They wont really give those free coins for sure.
