I have read in Bitcoin.org site that some wallet and developers supports 2X. Ok, that is fine if they want to but what calls my attention is that Bitpay supports 2X and Bitpay is related to the wallet Copay.
So my question is: Would my BTC stored in Copay be compromised after the hardfork?
I know Copay points to a Bitpaywallet but what if they go rogue and change all the BTC to BTG or whatever after the hardfork?
Does anyone how could I get my own bitcoin node wallet service URL to change it in the app?
I expect that won't work, Bitpay won't willingly make it easy for Copay users to avoid their hardfork. Best course of action is to export your keys to use with different wallet software, and keep the Copay wallet for when you want to dump your B2X coins when the airdrop happens.
Be careful to follow best practices to avoid replay transactions (maybe if you swap Copay wallet for BTC wallet when making B2X transactions, you could use the replay protection that apparently exists in that software, but it needs to be selected as an option, it's not a default option)
