Thanks for your concerns. We will actively check out all cryptos! It would be ideal to leverage the technology that has been built through bitcoin and something we will look towards.
Glad to hear that. Some additional info then: Counterparty published an Ethereum version built on top of Counterparty. Ethereum responded by building Counterparty on top of Ethereum. The obvious difference is that Counterparty uses Bitcoin's blockchain and security, while Ethereum has nothing. To makes things worse they use PoS which we know can't be made both secure and decentralized at the same time. That's why all PoS coins are centralized through checkpoints or whack-a-mole style security patching.
