Why I only use STP or ( steem power) - My long-term Investment on Steemit ( how to become a whale)

Steemit is a unique social media platform that is basically Facebook + bitcoin  but steemit is a tad bit different. You as a creator or blogger has a chance to choose three currencies STP,Steem,and SBD which is how a blogger gets paid ,but I use 100% Stp because the more power you have the more your up-vote is worth. Sellf up-votes  are the way to grow on Steemit or D-tube and  you have to appeal to the audience so if you were to see a whale with 300  dollars per up-vote because the whale  probably saved up steem power.
