As much as the article is from cointelegraph, but it's half-baked and disappointing. It provides no data to show how popular the apps are. I don't have an Apple device, so I decided to check out Google playstore since Android has way more users than iOS and the trading apps aren't even anywhere close to the social media apps.
Facebook - 5B+ downloads
YouTube - 5B+ downloads
Tiktok - 1B+ downloads
....
Coinbase - 10M+ Downloads
Robinhood - 10M+ Downloads
So I don't know what cointelegraph is basing on.
Total download numbers can not be used to judge the growth pace. If you want to compare the growth pace in a month or during recent months, you have to assess stats for one month or a few past months period, not All time in history of each application.
It is very normal if applications of cryptocurrency exchanges have exponential growths in recent months. I recalled that Binance or Coinbase have their reports that their new registered users are growing very fast.
