As long as you have the private key it isn't going to matter what wallet you use, the only thing you need to be careful of in the event of a chain split is replay attacks which is where they can resend the transaction on the other fork if u send a similar one on the other chain.
Thanks.
I've decided to move most of my funds away nonetheless.
Another reason was the copay/bitpay two version issue, and a client without password protection. Also because the team didn't come out and issue a decision about Segwit2X.
Kudos nonethless because bitpay felt like a super user friendly client with great UI/UX.
