I don't think so! Blockchain can be a career for a very few percents of people who are too expert at it but otherwise, it's no! Just look at your side, how many people you see choose blockchain as a career? Almost 70% of the crypto project won't last for 5 years, then what will you do after 5 years? What if bitcoin price goes under 2K USD? you can't ignore this possibility! I suggest do a job, take crypto as a part-time earning method!
