RE: If you could write a letter to HIVE owners on exchanges, what would you say?

For sure if they're Canadian, they'll be saying, "Sorry."
^{Based on stereotypes, that's just how we are, even when it doesn't need to be said. And it's true...}

If I was taking part in a project like this, I'd pitch the idea of being able to convert downtime/leisure time into a way to earn money. I feel when it comes to promoting Hive (in general), the idea of earning simply by showing up to be entertained is the most neglected of all opportunities available here. So easy, even a child can do it.

And I'm certain majority of those producing content here would enjoy the benefits of having more eyes around. Then those eyes spread around to the other projects, and these people begin learning about new things. Before you know it, you've attracted a new long term investor and community member.

Always wise to make the first step the easiest. That's why all those big money making stores have automatic doors. But I realize that's not what you're looking for here, since I guess boiled down it would fall into the earning of curation rewards category.
