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, and I wonder what kind of work did you do 13 years ago? A person's life depends on workability 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.
There is no longer free money anywhere and for one to make something meaningful in this space, it will require skills and patience to wait it out and the learning period is not always easy for newbies most especially those that choose freelancing and investment as an escape route from poverty or an alternative source of income, instead of building a motivational foundation that will sustain them through the process of learning and equipping themselves with the relevant knowledge that could guarantee a glorious future for them. Cryptocurrency is not just an investment scheme but also a technology that requires adequate knowledge and skills in various areas to be able to maximize the potential that is embedded in this young fast-growing industry. But if a person focuses only on the profits aspect, there will definitely miss out on the most important instruments that will guarantee them a smooth and less risky crypticurrency journey and having other skills as a backup plan is definitely another good way to sustain your financial stability in a time of uncertainty.
