Probably the best way is to google the right questions. Searching on here isn't that intuitive yet.

I can summarize quickly for you though. Your account has a certain strength, depicted by money.

If your wallet has $1,000 for example, you can put that into 'steem power' (check your wallet to see that), and that $1,000 will grant you about 8 cents of voting power. This means all your votes will give people 8 cents each time.

If you make good stuff, more people and more powerful people with say, $500,000 dollars in their wallet upvote you. Your post makes $40 and 7 days later you can put that into your wallet to increase your voting power. Over time your vote becomes stronger and so on.

The problem I talk about here is that the huge users with millions of dollars have votes worth $50-100 a pop. They can sell that as a service to individuals who can then upvote their own content for $50, even if it's just a single sentence or meme. It means only a few people are taking all the money that exists on the platform and it basically collapses, and everyone is looking for a solution. I think mine is the best!
