Back in the days, when no one knew what Bitcoin was and no one cared, people got free BTC for attending a speech about it. To make them care they need to have some.

I know this is not the same thing exactly, but your post did make me remember faucets being such a thing.

I still sometimes load up a reddit tipbot with Dogecoin and just randomly drop a bunch all around for no reason. There was a Steem reddit and Twitter bot being worked on https://steemtipper.com/ . People definitely sometimes need to be given some to see how or why these cryptocurrencies work so well and pretty straightforward after the quick learning curve. Crypto Greeting Cards are still one of the best ideas out there imo. I believe a few Steemians did art for some of the cards. Great gift idea for nerds and youth!
