While Charities seems an awful scammers these days, we are sure that Charitybot is not,
And in reference of Etherdrop, it is a transparent verified smart contract, you can check the smart contract on etherscan.io , the source code is also open for everyone and guided on codeproject.com
Give it a try and support, we support charitybot as well!
We are in a startup phase, and more prices and improvements will be upcoming soon,
Thank You 😊
