It depends if your full time in crypto gives you ten times salary than your real work then you can choose crypto. The only thing that we are sure about crypto is if it will still continue its existence in the future. There so many benefits of a real job in the long run.
That depends on your location. There are countries where $500 is worth hundreds of thousands, but if you give that $500 to someone living in the U.S it wont be sufficient for them. So I will prefer to quit cryptocurrencies completely and work in companies like Microsoft, Apple and Google where I will be getting paid hundred thousands of dollars as a programmer. So it all depends on. Your location.
