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.
I find this question very boring, Bitcoin is only 10+ years old, I wonder what kind of work did you do 13 years ago? A person's life depends on work ability and skills. My teacher once told me that it would not hurt me to master one more skill. Now the crypto world needs more patience, if you speculate to make money, the answer is that you will go broke.
In most of the answers that I read, I find that people are still in the confusion of mastery of crypto and blockchain applications, and between trading. Crypto and trading are two different concepts, although they are closely related.
Crypto can help to manage projects and enjoy useful features. It is assumed that this technology is very useful in the context of developing skills and passing them into practice. Trading is a form of gambling and cannot in any way be relied upon as a major source of income.
