It is unfortunate when fraud abuse or just plain negligence occurs anywhere in the financial system including the internet. You made an interesting comment about Crypto Exchanges being The New Wild West. That only means the Potential for Corruption Exists, it doesn't mean it's there.
As with Brick and Mortar Online Exchanges the trusted Crypto Exchanges are and will be those who prove they are real by either processing transactions and offering the goods of sale or by offering refunds when products are not received.
