if I do not have enough skills and knowledge about cryptocurrency then I think the answer is very simple, that is by learning and continuing to learn. With real intentions all can be learned.
I have contracted with ICO, I follow social media campaigns, create articles, etc. maybe it's just a bit of money-making work, and much more that I still might not know and need to learn again. But the problem with having this job is that you will also be risking your time, and also when the ICO is successful then you will get the rewards but if not, your time and your work is just wasted. Also in terms of income, your income will also depend on the success of the ICO.
This kind of work is also temporary so it is best to have your own job as well as a side job with cryptocurrency. you can also create a new business as your daily business.
