Crypto triva

Hello all, I have gotten a few people into crypto this year, my brother, my sister, brother in law and a nephew..

Have been sending them a few hundred each, but now I want them to actually learn for themselves how everything works…

So instead of just sending them random amounts every so often, I'm making them answer questions, and the WINNER gets $50/100 worth ( depends how generous I feel each day)….

What are some CRYPTO questions I could ask? Cheers and thanks.
