Re: How can this be good for the cryptospace environment in the state of New York?
I am seriously not finding anything wrong in this move of including two crypto businessmen in the task force. It could have been much more worse not to have these leaders in the task force. At least these people will ensure that things don't turn hostile for the crypto users in the state of NY.
Agreed. From a regulatory standpoint, what's good for Ripple and Ethereum is also good for Bitcoin.
I do not entirely agree with your statement that, " From a regulatory standpoint, what's good for Ripple and Ethereum is also good for Bitcoin. " The BitLicense was a blow to the NY Bitcoin operators, because it placed a complex and expensive barrier to entry for anyone that wanted to use Crypto currencies in NY.
BitLicense was introduced in 2014 and was bad for all cryptocurrency services -- whether they served Bitcoin or altcoins. What does that have to do with Joseph Lubin and Ryan Zagone being appointed to the Digital Currency Taskforce two days ago?
Ripple is also not a true Crypto currency and Ethereum is Bitcoin's strongest competition and having them getting a stronger foothold in the economic capital of one of the strongest economies in the world, is bad for Bitcoin. 
Could you give a concrete example of how this could hurt Bitcoin?
