50 million users? Wow that's a great idea. What if each user's posts had no daily limit for payments. Every post will always be upvoted, every upvote there will be a payment even though it has passed seven days. This means that upvotes that come later will take effect and become payments for the next seven days. Every upvote is systemized with time. For example, if an upvote is given at 1 o'clock on the 1st, a payment will occur at 1 o'clock on the seventh in the future. This is indeed a stupid idea from me, but every post will continue to be valuable forever. Like Youtube. Thus every post on Steemit will not be trash.

Next, make strict rules regarding plagiarism, because this will be a valuable and useful blog for every visitor.

No tolerance for plagiarism.

I am not a developer, but I am only giving suggestions for this amazing platform.

Thank you.
