I withdrawal my bitcoin to electrum.There you can control the keys and you cant have worries about that bro but I am 100% sure that from bitcoin will not be born another cryptocurrency so there will not be splitting for sure.
The BCC coins are sure to come. I 'll have to get prepared. BCC is a hard fork. They may compete with BTC directly in near future. I never tried electrum. I will give it a try. Do you have to wait a lot of time for syning?
There is no guarantee that there will be another coin. But be on the safer side and transfer all your Bitcoins to a desktop or mobile wallet. If you control your private keys then you'll be safe.
