What you say is true, If we look at the title of the thread it is like that, but when you visit their site you will find this statement:
Blockchain: GETO Blockchain Network
Consensus: Proof of Staked Authority
Native token/currency: GETO Token
Ticker/Symbol: GET
Virtual Machine: EVM compatible
My conclusion is, maybe at this time they will use their own blockchain which they might be working on, later it will be created so that this token also has an eth and bsc blockchain. Simple as that, it's just that we don't know when they did it.
