I finally found the reason why the newest Worldcoin clients source code still hasn't been made public.
The new client is extracting the private keys of your wallets and sends it to an external server.
Some weeks ago a chinese investor reported that his Worldcoin got stolen.
I am sure that the dev team exactly knows who owns the stolen Worldcoins now.
This is a really nice and new idea about stealing money from the community and getting the last cent out of your scam coin.
Good job guys! Worldcoin will go to hell now.
My advice: Stay with the old client! This one doesn't steal your coins.
And never trust any of those newer versions! They all can possibly steal your Worldcoins!
