Best way to explain Bitcoin in one paragraph

[9kv]

I'm looking for a paragraph that explains Bitcoin in simple terms to share with my friend. I would write one myself but I am still learning a lot and I don't want to mess up any facts.

Thanks so much in advance!

BTC is a protocol, an open source technology, a medium of exchange and a commodity like platinum or gold

Advanced version: it's like an API for programmable cash transactions
