Note that you can’t have two wallets minting with the same coins simultaneously because they will find the same kernel at the same time and the netwrk is designed to reject duplicate blocks. You block will be orphaned.
I thought there is a way to work around. If you have your raspi minting all the time, and you want you laptop to take over with hte same wallet, you can adjust the clock of you laptop to get ahead of time by 6 minutes, so that your laptop will find the block first, and have the network to confirm it before the raspi also finds it. This didn’t quite work out for me because my laptop and raspi keep sync’ing thier clocks back to the correct time and I can’t bother to spend more time on it. Please report back it this works. I would also like to hear from @sigmike or other devs whether this practice is not going to work or not good to the network.
