I've looked at their site today and just like I thought, they have very inaccurate info.
Outside of splinterlands their site is only showing 14 active wallets across all other games. Also no money or trading across most of them and missing other established games.
These sites are never that bothered about good reporting and it took a lot of messages over and back with coingecko to get our page updated properly.
I've sent a message to @DappRadar and the plan now is to get their team to work and fix the hive stats. One site at a time if that's what it takes as these are important marketing channels for the chain.
