Dear all .. only upvoting will not work 

you can see that this post has 89 upvotes but only made 0.64  

you can see lots of posts with less than 5 votes but has a lot more valuable rewards than this .
so why is it so 

i will tell you guys 

there are a lot of things that matters while voting 

STEEM POWER  and VOTING POWER 

so basically having very less voting power does not make any sense -- 
and upvoting each comment on this post and the post itself is useless...

first you need to see your voting power    check here 

steemd.com/@yourusername

there you can see what is your voting power and your steem power 

if you have 100% power and 15 SP which normally new users have then your 100% vote is equals $0.01    and if you upvoted one post then you loose 2% of your voting power --- and you also generate 20% voting power every 24 hours .. 
so best practice to make a good sum of money in steemit is only voting few posts a day and posting one post a day ... commenting on at least 10 posts....

i can explain you how curation reward works and how easily you can make money by curating someone else post... if my comment reaches $10 ..
