User acquires an/a set of in perpetuity futures contracts. (A future without an expiry date, effectively, what? A pin I guess?) Idea being, this order indicates intent to swap at volume $MNGO to $USDC at $RATE.
Centralized exchanges sees the futures order, and starts cranking up the price of $MNGO due to the increased interest in swapping based on the presence of the Futures.
The Futures contracts are leveraged, but require no collateral, because there is no expiry date on the Future (no intended date of delivery).
So the order volume (spot token purchases) induced upward price movement and... What? Caused other uninvolved investors to buy his acquired tokens at a peak, and he just takes the money and cashes out never intending to actually honor or settle up the perps, which won't margin call, because they're still "good" but will never mature? I'm failing to see an exfil path for ill-gotten gains/financial chicanery beyond the seemingly obvious wash trading.
If anyone can help detangle this, I'd be much obliged. This kind of market weirdness is interesting, but inscrutable at times, when there's usually like 6 pieces of networked jargon needed to render something that doesn't tend to line up to anything tangible in the conventional sense.
