Well, it's very risky to work as a trader/investor in cryptocurrency as a standalone, full-time job. I always saw my investments more of a fun, rather than a way to gain huge profit - still I have hope to become a millionare someday, be let's be honest, it's too risky for me. I don't see a problem to work on a full time job in the industry, for a company.
Those affiliate programs (like
https://www.cryptogamble.com/affiliate for example) are very cool way to earn some money in a long term period of time, without investing your own money. From what i see, there is ETH and BTC are available there, and I used to gamble a lot some time ago in an online gambling platform, and right now I was thinking of gettin back to it, so this CryptoGamble could be a chance for me to not only have some fun (maybe win some, maybe lose some haha) but also to create a nice profit from affiliate program.
