Just imported my electrum BTC private keys into the BTCP Electrum wallet https://www.electrumbtcp.com. Worked fine without any bugs. Good work! 
is it safe to use bitcoin private keys? It looks dangerous to me.
Personally i don't trust to use privayekey.. With Trezor i would need to do a reset of seed and this requires a lot of effort and time.. Is there not a better way to claim btcp? Or at least some trusted agency that can conform it is safe to share private key?
