The negative yield would be that I would have turn 1BTC ($55K) into $13,500 by buying delegation from 90 days delegation from blocktrades.
If you are an investor who want to add capital to a project, HIVE seems to be the worst choice to get a yield. It locks your money away for 13 weeks, you have to be super active to "maybe" make money and when the market turns and you need to lock in your gains or prevent loss, you are roadkill for 3 months.
