What is the coolest thing you’ve done with crypto?

The title says it all. So, what is the coolest thing you’ve done with crypto?Have you ever bought anything neat with it? Paid off some life changing expenses?

A few years back I’ve bought an hardware wallet by using Bitcoin. That was my way of ‘taking profits’. It wasn’t much, but it felt great to be honest.

I also once amazed a few friends by showing them how incredibly quick you can transfer assets with Algo. (No shill, I don’t hold Algo anymore) I had them set up a wallet, and send them a little bit of Algo in a matter of minutes. It helped them to understand the essence of cryptocurrencies.

And making free money because I participated in some airdrops was cool as well.

I’m sure there are more amazing stories than my lousy examples. I would love to read them!

EDIT (after a lot of comments) -

In summary of this topic; I've read so many amazing things people have done with crypto.

Browsing trough this sub I came across a topic titled: 'Cryptocurrencies add nothing useful to society, says chip-maker Nvidia'

Well, how wrong can they be. Sometimes it's about the small things.
