How many coins do you need to get a stake a week?
I think you should have a look at the cloud (cloud.stakenet.io) for one stake a week it seems a little ineffecient to have the wallet on 24/7.
I think its much safer to be in control of your coins , right ? If you can't manage your pc to run 24/7 then yes, you can try the cloud from stakenet. Also read above that sometimes it will take some days to withdraw coins from there so if a pump happens what will you do in that situation as like I said your not in full control of your funds.
