how does one create a 2nd wallet for spending?
If you move wallet.dat out of it's folder a new empty wallet is created automatically.
but then u can't send btc to that 2nd wallet from the 1st wallet on the same computer. my goal is to save the majority of my btc on a flash drive in my safe and not have to pull it out for several months. then i'd have a 2nd wallet with spending money on my computer. should i just send the btc to a client on another computer? is the wallet.dat file interchangeable btwn mac and pc clients?
