I have been doing a contract with new ICO's, I have been a social media promoter, project advisor, community manager etc. But the problem with having these contracts is that you will also gamble your reputation, when those ICO's succeeded then you are thankful but if not you are risking your reputation to waste. Also in terms of income, your income will also depends on the success of the coin since they will only give partial payments before ICO and the rest after the ICO.
This kind of job is also temporary thus it is best to have an office work at the same time a sideline work with cryptocurrencies.
very true, Cryptocurrency very suitable side jobs to supplement income. However, there are also those people who resign from their original jobs and work only in cryptocurrency such as trade, mining, or following the campaign.
