As the title says, is passive earning from Bitcoin is possible nowadays. Let's face the facts mining is very much expensive for most of the users and I have encountered with many people who think they do not have any skill or do not want to learn any soon. There must be anyway by which you can make money by using most of your time by investing only once or by a little investment.
It's like expecting a fruit when you don't even plant trees.
Yes mining requires less attention, but I don't think you can consider your earnings on mining big. You see mining would generate huge electricity bill because you'll be using a high powered computer for that and it will run 24/7. So most of your income with bitcoin would probably went to your monthly electricity bill.
Try room renting business, but you'll still do much work in chasing your tenants during payment times
I think you need more attention to this and also required maintenance for mining rig. If you have a little amount of money. I suggest that you buy token and stake it or Masternode.
