A very bad move on their part, people will stop using them. Now that they have KYC they are no different than any other big exchange and with funds locking up, less reliable. It's a shame to see this, because KYC is a very burdensome process in a lot of exchanges.
Another one bites the dust... I don't think there are any left that do no KYC that I am aware existing.
