Thank you brother for this tutorial. I'm investigating and I read that he made an SP contract and then he sold the votes.
I calculated my SBD earnings from 18 December to 19 January just from vote selling and they turned out to be 55.695 SBD. This was made possible because I had used another MB service (SP leasing) to get some delegated SP for four weeks for just 25 Steem. Through vote selling alone, I earned so many SBDs that it was more than triple of my initial investment.
I would give some recommendations for the lease of SP, what parameters should I follow? I'm a little confused about NETT% APR. I had not done it before because voting for yourself would be as selfish as you say. But now I know I could sell the vote.
