About the votes: I see that you know how to vote. You just did it in my comment, in the same way you can vote in the publications. as you see after voting the comment step to be worth 0.01 $, that's what a vote of yours in steemit is worth. The vote value depends on the steem power, you bought 42 steem and converted them into steem power, if someone has 4000 SP your vote is worth $ 1 but it is not 1USD, but $ 1 that is shared as a cryptocurrency in SBD and SP. Also you can not vote whenever you want, there is something called voting power that decreases each time you vote and recharges with time, is measured in%, one vote decreases it by 2% and that 2% takes two hours to recover, If you lose 80% your vote will no longer be valid until it recharges, I recommend you to stay at 90% giving 5 votes a day. You can check your voting power and the activities you do in steemit using the steemd.com/@usuario tool where the user is the person to whom the data you wish to consult correspond. for example you can see your voting power in steemd.com/@jbz
