I practiced earning money on groups in a telegram, but the point was to create a channel that you actively replenish with certain information. You gain traffic [of people], and then you actively sell ads, not forgetting to write your username in the group description so that people can buy ads from you. When you buy an advertisement, you post a post that the customer requires from you (in most cases this is for a while, so as not to clog the group)
A friend earns 12 thousand rubles for a twenty-minute post on his channel. Users are appreciated in the telegram, in connection with the target audience and active people. Accordingly, the price of advertising is high. You can place your group on the website exchanges by telegram groups.
I hear about earning money on assignments for the first time.
