How can I get MAPO swag giveaways?

I saw the pics of MAPO swags at Busan Blockchain Week. I’m wondering if the team is doing or will be doing some kind of swag giveaways?

With the swag giveaway, we can even run a twitter campaign for that — asking the winners to post a picture the swag and mention MAPO’s twitter.

Do you think this is a good marketing idea? Or how can we make it work for good marketing results?
