Hive account@steemitbuilder looks ok however i can see a few issues.
First is you don't own any shares. Not a deal breaker but you have to wait a long time to get back your original share value before turning over a ROI.
Second they have a large sponsor if they decide to pull out then the value will drop. Sor far they have around 140 owned sp and 2500 delegated sp.

Full disclosure this account is also Hive account@andrewharland. I do have a vested interest in minnowbuilder. However this my truthful opinion. I own a lot of sbi and think that was/is a great program but the cracks could show if they can't keep up with the purchase of delegated sp.
