I think, it is really cool, that you can earn with Telegram, but you should be careful in order not to find SCAM. I'd recommend to find a crypto signal service. But, it's quite difficult to find good one. For most major services, advertising SCAM - a good way to earn without investment, because SCAM pays for advertising costs on crypto platforms.
To choose a cool service, I would advise:
- Do not look at the advertising of the service and its scale;
- Read reviews on the Internet. Usually, if people get from the service to SCAM, they have nothing left but to write a negative comment. So I advise you to pay attention to it.
- Attend the thematic forums. On them, people often share useful links.
- I myself got a couple of times on SCAM, so I create my service, check it https://safetrading.today/
