Having sold a couple of .coms with crypto in it, I tend to say yes. These were however aged domains and I registered them long before crypto got its current meaning. Before, it was more about encryption, cryptography, cryptology. Think of VPN, HSM, TLS, SSH, PGP, etc.
The current crypto market has to do with payments, blockchain, alternatives to traditional banking, etc. There are lots of initiatives and startups in this area, some useful others crap.
Try to read about these technologies in threads here on namePros and try to create a gut feeling which short one or two worders describe the field. Eventually, register some names. You may be optimistic, but never forget you are competing in an extremely crowded market. Most registrants are late in the game and will not succeed.
Hope this advice doesn't sound too cryptic. Wish you good luck learning, investing and selling in this interesting field.
