Participating in crypto related work is risky. What if some of the projects turn out to be a scam or there isnt enough market demand for the projects you take part in. All that will lead to lower or no money at all for you and its not worth the risk.
Always do apart of your income because only count for 1 job is very risky. Do more than 1 job to save your income because this is about life. Never believe into one job because sometime our job can be stucked and our financial will be problem. Actually doing full time job in cryptocurrency is very hapoiness but its not our only goal, as my financial not so good so i prefer save my financial by doing 2 jobs.
