I am not here to judge anybody. I don't have spare money to invest into Steem Power (If I counted it correctly, 100 Steem Power gives you about 0.035 USD per vote and cost aprox. 165USD).
So I just try to do my best and together with my friends we are building up the Czech community, since we all believe that Steemit's future is bright. And we want to help our fellows, most of them don't speak English enough to be able to write English posts. It is not easy but we believe in it. You can check it yourself: #cesky.
If I invested money into SP, I would most definitely support my mates and myself. It is an investition and I would expect some revenues of it. As anybody else. But still, I believe in sharing, mutual respect and donating, hence i wouldn't kept my voting power for myself.
Still, it is just a therory. Send me about one million SP and we will see :))
