Great question! I would certainly quit my job and live off Steemit. Then I would have a lot of fun giving massive upvotes to random steemit users. I would feel a lot like Santa Claus! I would do some renovatiions on my home, and sponsor a number of people from Venezuela with 700 Steem Basic Income shares each. (That is the maximum number). Then I would pursue my screwdriver invention full time. It would change my life a great deal, and the lives of many others.
