EtherBTC is a hybrid cryptocurrency that offers an immutable supply of just 21,000,000 ETHB, combined with the speed and affordability of the Ethereum blockchain, to provide a stable currency that can be stored in, and exchanged from, any Ethereum wallet that supports ERC20 tokens.
EtherBTC combines the best of bitcoin and Ethereum to create a hybrid cryptocurrency that is fast, inexpensive, easy to use, and stable. EtherBTC is not a security … it’s a new, decentralized, peer-to-peer currency in the same family as bitcoin, Ethereum and Litecoin. No more than 21,000,000 ETHB will ever be created, the same maximum number as bitcoin.
