Steem power delegation is amazing that will help you to grow quickly on steemit if you don't have enough money to buy steem power. Its very difficult to get delegation now a days. I bought steem power delegation on blocktraids price of 8 steem per steem ( i got 5020 steempower by giving 575 steems for 3 months)which is very costly. I did not calculate before buying. I want to inform you that please don't buy steem power delegation from blocktrades for now. If you are good content creator and want to expose your content through self voting then you can buy steem delegation from blocktrades it is still available. Thanks for education post @swissclive and minnowbooster tutorial.
