Well, I looked at your stats, you will have to wait 4-5 days to recover to 100% of voting power. No voting suggested in this period. The price of upvote depends on Steem Power, not reputation. You have rewards for your activity on the site partly in steem power (SP), partly in steem dollars (SBD). You can convert earned steem dollars into Steem (token) and then convert it into fiat carrency, keep as cryptocurrency or by a SteemPower. The last is called power-up. As more steempower you have as bigger your upvote sum. You can buy Steem for your money and then convert it in Steem Power - to become investor, but remember the back operation is not so easy - converting SteemPower into Steem (powerdown) takes a lot of time.
