Until steeit changes the code to not allow you to upvote your own posts I see no issues with upvoting them.
I've 100% powered up (no sbd rewards) several articles and completely agree that if you believe in the long term value of steemit everyone should be doing exactly that unless they have time to watch the market all day everyday or have taken the time to understand the market and when the best time is to convert your SBD to Steem.
You may have been forturnate here on Steemit, but you can't say your sucess has just been fortunate because I see the "grind" you've been putting in.
Thanks for the kind words.
I know I have probably put in more effort than a lot of people, but, unfortunately, it still does come down to a bit of luck when it comes to a big payout for post.
