I've got a bunch of CD disks. I could put a video about how to invest in crypto on them. Every exchange I know of has a referral fee so I could make money on them.
I've just got to get off my butt and make the video somehow. I figure I could make one, each, for Kraken, Coinbase, Binance, and Gemini.
If I give them away, I might get tons of referrals. It's worth trying.
I think I'll link Alux, here.
