I'm pretty new to this site, and when I signed up I transferred about $100 worth of BTC over to Steem power. After using the site the past couple of weeks, my wallet estimated value was hovering around $108 for a few days. However, now it is $99? How is it possible to have less than what I started with on this site? Especially a 10% decrease in a matter of days, at that? Something seems fishy about Steemit if everyone claims you have nothing to lose, yet my posts are not down voted or flagged and here I am losing. Am I missing something here?
