The concept of merging bitcoin and ethereum is good but not unique. Qtum does the same and is years ahead for development. However, as a new coin to mine this bithereum could be a good choice
Qtum is for sure an excellent project, however there are slight differences. Whereas Qtum has taken the UTXO model and built it into a modified Ethereum or smart contract platform, our goal was to build a modified Casper PoS model (with additional Ethereum scaling solutions) atop of Bitcoin, allowing BTH to be solely a p2p currency, as opposed to a smart contract platform.
However for the foreseeable future, our PoS implementation is laid out in our Proof-of-Uptime program where all full nodes get incentivized based on the amount of time the node is up. No actual staking is required however holding more BTH in your full node wallet will allow you to receive additional rewards.
This means that mining will be around in BTH for time to come, which is good news for you
