Since the exchange is decentralized, I think it should be possible to see if wash trading is happening with some detective work, right?
I mean, if the price action is due to the listing on cryptopia then there's probably someone with deep pockets buying up whatever is on the offer. It isn't a whole lot of money that would be required and this is the first we've had some big news items coming out in a while (that and the recent bit of asset layer hype). Either way, someone is buying, and I bet there are some trapped miners who need to pay their electric bills seeing the price move up and are depositing their RVN into the exchange or selling RVN that they have had loaded into the exchange for a while but just in storage without any orders placed.
Edit: and the detective posted his reply just before mine! lol
