Smart move. CENT currently has a decent inflation rate which means that you should start getting decent curation rewards when you upvote CENT content.

Here are a few tricks. PeakD.com lets people examine different HIVE wallets. This page shows your HIVE-Engine Account:

Sure enough, your CENT is listed at the top of the page.

Your wallet shows that you have 18 HP and a 40 HP delegation. That gives your account 68 HIVE POWER.

I would like you to go to your activities page:

@isaacngore/activities

Click the box next to the word curation. You are likely to see that you are not receiving very many curation rewards.

HIVE rewards come from interest on your HIVE POWER. The minimum curation payout is 0.001 HP. It turns out that you need to have about 80 HP in your account to start getting curation rewards on all of your posts. You might want to concentrate on raising your HP to the level where you get a curation reward for all of your upvotes.

Good luck on building your account. A good way to learn how HIVE works is to study the wallets of the different accounts and you can see how their investments affect their vote values and interactions.
