/*

Hentai ETH is an upcoming crypto currency on Ethereum chain which will be used as a currency to pay on Hentai Pornsites. 
The currency will be used as a payment method for all kinds of adult content and services. It will be a decentralised 
cryptocurrency which aims to provide privacy and security for its users. The currency is strictly designed to pay for 
Hentai porn and we are going to capture all of the Hentai Market.

We are going to do a lot of big collaborations all over the internet , our to be partners are : HentaiStigma , HentaiCore and Rule34Video
