Vaultoro discarded its support for the New York Agreement (NYA) with Bitcoin, because SegWit2x developer Jeff Garzik proposed using opt-in replay protection, whether Vaultoro demands opt-out protection for its users. Opt-in replay protection means that it should be activated by users manually, and it is considered inconvenient and useless by the company.
2) As any good businessman, I stick to my word / signature and would have followed through with 2x but I cannot without replay protection.

What is more, Joshua Sigala wrote in Vaultoro blog on October 24 that at the moment the company does not support Bitcoin Gold hard fork either, because it is important for exchange platform to see that other platforms, services and wallets like, for example, BitPay support the hard fork too. Moreover, they are disappointed that the developers didn't make the code available for review so they will not be able to audit or review the code.
At the time of a fork, Vaultoro will snapshot every member's bitcoin holdings and if Vaultoro decides to support Bgold or any future altcoin released via a fork of bitcoin, customers will be able to withdraw the altcoin associated with their Vaultoro Bitcoin balances at the time of the snapshot.
It is also stated that they will continue to follow the development of forked coins and if new networks prove themselves to be safe and useful, Vaultoro may decide to support that asset at a later date.
