Yea. Welcome dear for finding the post useful.

For your question, I can guess you're asking one of this two things:

1. How you can increase your upvote value so that when you vote on people's posts, they gain more curation rewards?

For this part, you have to allow time play it's role here. As you must have significant Hive power to be able to do this. Though, you can hasten this process by buying more Hive coins and staking them through the power up process.
The more your Hive power the more your vote value.

Another way is to have people delegate Hive power to you, the more delegations, the more Hive power. But gathering delegations will be easier when you have a huge presence on the chain.

You could also build a curation trail so that you basically gather the hive power of numerous users into one under your purview, and when you vote on a post, everyone on your trail votes on it automatically, thus, increasing the vote value

1. How you can increase the rewards you earn through upvotes

This also takes time and work. The longer you stay on the chain, the more connections you build, and the the more your presence is felt, then you'll likely receive more votes. You may also join some communities and post boosting and promotion services at your discretion.

Hope, I've answered your questions!
