It is great for the lessor, not so much for the lessee. Remeber, they also have to pay a 10% fee and don't get the Sp inflation. 28.6% per year is a tough yield to base an IRR off of for profitability.

There are lots of good business ideas, but not ones that can make 28.6% per year. Steem is 34 cents, 10k steem is a 0.1956 upvote, you get 10 a day, so say 1.956 to be generous as most won't be at exactly 100%. 10k steem costs 2860 per year to lease. 1.956*365 is 714 dollars. 714/0.34 is 2100 steem. Now remember you wil have to share some with curators and may be downvoted for so much selfishness.

I don't see why the market price went up above 21% except out of desperation or to run token based pyramid scams because the money is flowing in now and the markets are hot.
