Couldn't be more correct. Today, participating in cryptocurrency is not just about becoming a trader, investor, or participating in bounty campaigns...we are growing and have full-time jobs like working for a blockchain company, KOL, researcher for venture capital firms, blog creator, video...It can be said that today's crypto-related jobs are almost the traditional jobs that we used to have. So as long as you have any skills related to them, you can consider it your main job, a full time job. But it's good if someone can diversify their source of income, I also prefer to do 2 or 3 jobs rather than just one job.
Nowadays have thousand kinds of job available in cryptocurrency because not only as trader or investor but also we can participating as Bounty campaign, blog or content reviewer about cryptocurrency, become moderator for several altcoin project or could try to be local telegram exchange market and have many kinds job list in cryptocurrency. I think realistic when cryptocurrency become full time job, but need time and progress how to earn much income with cryptocurrency actually with passive income become reviewer on content cryptocurrency creation.
Better if want to make cryptocurrency as full time job not only depending with trader or investor but also find several job seems team telegram support for altcoin project, make review with content creation or could make video review and advertising when have new project launching.
