Alien cryptos?

So after the UFO hearing today at Capital Hill, one of my first questions was if aliens truly are real, then what do they use as money, I don’t think USD will be a currency that suits them very much. Do you think they all use crypto and if so which one do you think they are trading cause I want to get the jump on that one. Also US Gov we would like some NFTs of their spaceships, when do you think predicted date for those will be? What are you guys predications on crypto do you think that’s how we will be trading with them, or on the other hand so you think we will be plundered for our BTC?
