I am a delegation to upvote bot were i offer a daily upvote to delegators. I am able to offer a ROI of between 140-160% and it is another way that users can invest SP. To get the best ROI you would have to post everyday and this is not for everyone. There are many other options out there apart from delegate to receive a daily SBD/STEEM payment. Great post, was a really good read. Thank you
