Yep so far, there is no regulated exchange in crypto space, But soon there will be, I don't want to drop name but there is some exchange working on acquiring a license which guarantees fair trading for all traders. No-wash trading from the bot and fake pump and dumps. I believe that this unregulated exchange will be extinct soon. Check out fun facts below;
Coinbase is the most regulated exchange in the space. It has been that for quite a while now. We also have Bakkt. This however doesn't mean that there won't be any wash trading. It happens everywhere, but the difference is that if done wisely, it's hard to spot, and even harder to actually prove.
The Asian exchanges that generate like $500 million in volume every day don't put any effort into obfuscation of their wash trading maneuvers. If you think about it, why would they? The noobs who they attract through index sites such as CMC don't get to read any of these reports. They're a deer in the headlights.
Also, why don't you want to drop that exchange's name?
