Why not both I ask? Learning about crypto does not stop you from learning a skill, and learning a skill as well should not stop you from learning even more about crypto. You don't have to substitute one for the other. People who were dependent only on crypto are somewhat having a difficult time in this dump currently, for those who are still experiencing the dump, but have a skill that they are using to cushion the hard effect of the dump are doing way better and I am certain they do not regret it.
