Wow, the 500% gain you have isn't enough? Crazy. There is risk in owning bitcoin, so theres no such thing as a risk free bitcoin investment.
I think you should leave your bitcoin in that paper wallet until segwit and the fork talk have passed. Segwit2x is scheduled to occur on August 1. And then the nodes and miners have 6 months to fully adopt the new code, so a fork is possible for 6 months past that Aug 1 date.
Just hunker down and enjoy the ride!
are you saying that if bip 148 is successful then also there will a chain split within 6 months?
Yes. There's a good explanation of it
here, scroll down to Segwit2x HardFork
Bip 148 is just a fail safe, if Segwit isn't already live by August 1st, Bip 148 forces nodes to reject blocks that don't signal for Segwit.
