Should the wallet always be running for minting? Or is it enough, to unlock the wallet once and then close it?
Wallet must be running for minting
Thanks, mein Freund

Another question. Is there any difference between staking from a single tx and staking with same amount divided in many txs?
Hallo mein Freund .)
1. You dont need to run Walet all the time for staking, its enought if you open it one time a week or month you will get then more cloaks at same time.
2. There is no difference between staking 1 Input or multi at same time BUT its simpler if u have one Input look for howto on forum:
