One of my friends are sharing a Telegram link which calls themselves as ETH Ads. They say that you get paid for each ads, and there's a referral system. This pricked my ears and I have a hunch that this is a Pyramiding scheme although my friend says that there's no need to invest some money out of it. My question is whether it is legitimate or not?
Clicking on anything shared on Telegram or replying to pm from unknown people can be very risky, or people are just sharing ref links, but I never heard anything about earning ethereum for watching ads.
I do know about a way for earning some altcoins for watching videos on odysee.com, and you can't get rich that way but it probably pays more than watching some boring ads.
Best way to earn Bitcoin and other coins is to offer your services and get paid in crypto, not just in fiat currencies.
