Assessment summary

Promo channel of a betting app BigMumbai: the feed is almost entirely repeating banners with bonuses, deposit screenshots and links with a referral code, diluted with "good night" pictures.

With 411 thousand subscribers, the median post gets 12 views — a fraction of a percent of the base, whereas similar channels in the catalog average 17.4% ERR. Over two months the subscriber count dropped by about 59 thousand, and the median views fell from 216 to 12, so only a small part of the claimed audience will see the ad.

About the channel

The channel runs promo for the betting app BigMumbai: posts are in English, mostly photos and videos with banners, deposit screenshots and links with a referral code. The channel is 4 years and 1 month old.

In the catalog, @flashe_coins, @cryptocoachbangladesh and @icc_toss_matches stand next to it. By subscriber count this channel is larger than them, but the share of subscribers who see a post is lower: ERR 0.0% versus 13.1% for @cryptocoachbangladesh and 0.8% for @icc_toss_matches.

What it publishes:

  • Bonuses and promotions: banners with deposit bonuses and "goal — bonus" tables.
  • Deposit screenshots: images of the top-up screen with circled amounts.
  • Invitations and free spins: a wheel of fortune and the rules of the "invite a friend" promotion.
  • "Good night" pictures: evening wishes with a city view.

Posts come out mostly at night (70%) and on weekdays (75%), roughly once every ten days; there are no forwards from other channels. By subscriber count this is one of the largest channels in the niche. The feed is mostly repeating ad banners of a single app, not news or analysis.

By subscribers, it ranks #5 of 43 channels in the Bets & Gambling niche of the catalog.

What to pay attention to

Very low reach: ERR ≈ 0.0% with 411 871 subscribers

Median views are a fraction of a percent of the subscriber count: a negligible share of the audience sees the post. The subscribers are there, but there are almost no views.

What grade F means

The index is at its lowest: the metrics fall far outside usual values, or Telegram has flagged the channel as a scam. See the “How the assessment was produced” section for details.

Channel content

📣 Heavy advertising load

The feed is almost entirely advertising for its own betting app: banners with bonuses, deposit screenshots and links with a referral code.

Compared with similar channels

Compared with 6 Bets & Gambling catalog channels whose metrics look normal. They are a similar size: 150,233 to 387,651 subscribers.

ERR (reach) lower than 6 of 6
@Crypto_Bigmumbai1_Mumbai 0%
similar channels median 17.4%

This is not a niche norm: only catalog channels are included. A high ERR is not always a plus: if the other metrics do not support it, the index goes down.
