Great analysis. Due to @blocktrades cheaper price, it is going out crazy, out of 3,674,489.074 SP, 2,137,879.109 SP delegated in one week. Therefore, it looks like there is a huge demand for delegated SP. What I think, @blocktrades delegated SP will be drained very quickly and @minnowbooster will see some users for their service too.
However, @minnowbooster offers 1-4 week service which differentiates it from @blocktrades.
@minnowbooster is practically begging for people to pick up delegations, so is there a demand??? Oh ya, big time.
