From the Apple app store link, people are giving glowing 5-star reviews that are titled "Earn Crypto for playing games", "Playing = making $$$", and "Epic btc".

From the same link, the app description says "Most users earn an amount that is only worth a fraction of one cent (USD)."

Pray tell, where is your targeted marketing finding people who get excited enough to write gushing 5-star reviews over being paid "a fraction of one cent (USD)"? On the first couple of days after release, no less.
