guys: can i mining with 2 machines to 1 wallet? or every machine must have own wallet always?
There's a wallet.dat file in your BiblepayCore directory (usually ~/.biblepaycore on linux or /AppData/Roaming/BiblepayCore on windows). Just copy whatever wallet.dat file you want to use from one machine and place it in the BiblepayCore directory on the other machine.
Yeah, I havent actually done that myself yet, but I have 'one' piece of info on that. Blue said he copied his one wallet.dat file over to 10 machines, and now on his desktop he receives notifications when any machine mines a block (IE the txlist updates). So he has one consolidated wallet.
I was going to add: In POW, since coins can be received in a locked wallet, you can encrypt and lock your wallet and still receive rewards from any POW device out there mining into that single wallet.
