Actually if I had a giveaway fund I could spare, I would have actually setup a system where I would educate others about bitcoin and cryptocurrencies in general and on top of it, gift them a small amount of BTC or any other crypto as a memento they can keep and recall about. It could be a placeholder or anything that is useful and makes you remember about crypto.

Regardless, I am sharing about Bitcoins every time I meet someone who doesn't know about it. Now with more legalization and laws made around crypto, it's easier to explain as well because I don't feel like I am explaining something illegal to my friends while they also have some confidence which earlier when bitcoin was new, was hard to believe.
