Is it possible to claim bze when my coins are always @ btcz android wallet ?
And if I do that will I lost my btcz current coins as I still hold them or I will just receive the same bze amount ?
You need to export the private key from the address that was holding btcz at block 160k.
You will have bze and You will not lose your btcz. Thery are two different blockchains.
