I think that if you invested some money, your steem power should be worth more voting power. IMHO. I started "aux natural" at $5, it's gone up $1.50 in two weeks. My voting power usually hovers around .01, but sometimes I swear I see people's money go up .20 cents when I vote...And then other times I get voted for by people with more SP than you, and my vote only goes up .10 cent. Not sure why the inconsistency. Yours should matter a lot more. But as far as the 10% drop, that's a bummer. Keep writing articles. Just pump them out daily or every couple days. You'll get some votes even if just small. Build a following, post good content, vote people up. You'll get it back quick.
