I know of Telegram channels on cryptocurrency with around 100,000 subscribers. During the bull run, these channels were earning $10,000+, but when the crypto winter hit, their income plummeted to less than $1,000 per month. I also know of a channel with 1,300 subscribers, but the author earns 20-30k per month, regardless of the crypto market. The manner of presentation and the level of information are very different: for the mass consumer, it's more entertainment content, while for a smaller channel, analytics and educational materials are a different level. Therefore, it all depends entirely on you: if you choose to write content tailored to your audience's needs, you'll degrade yourself, but if you choose to write content for a narrow audience, the audience will build accordingly.
