Looks like the data comes from Sensor Tower. The name is familiar if you're a gacha game player. I believe some of their stats are hard to verify, so always take them with a grain of salt. Even if this is true, I also think ranking them by downloads is quite flawed. There's a possibility of overlap if we consider this data to represent the numbers of new crypto users. Even if the placement ends up being true, I think they need better methodology to do this. CMIIW.
