Piggy bank is already a proven scam...
You can see this contract of Ethereum Treasure was first funded by Wallets with 70.000 ether and some with over 300.000 ether... so this are really big boys scammers... Just wait for Karma to come get all of you scammers !
This posted contract already buggued all deposits and transfers out are cancelled error... LoL
Hope you all burn in hell!
