The cost for a 30 day should be relatively similar to that offered by MinnowBooster, with some additional discount available for 90 day delegations.

Great initiative my dear friend Hive account@blocktrades. However, when I checked this above in your website I noticed something a lil bit confuse and hard to understand.

¿How comes that if for example: I pay 0.0050 BTC for a Delegated Steem Power (30 days) deal I obtain 1950.435 SP and if it is for a (90 days) deal I obtain 744.676 SP? ¡Almost 3 times less delegated SP for the 90 days deal!

Uhmm, something appears to not be right in the calculations according what I quoted above.

Please, take a look on this and throw us some clearer light about this mate. :)
