Why? Wash trading is about selling and then requiring the same asset for tax purposes. How is this analogous, other than that you presumably dislike both practices?
- "Our coin hit $100M daily volume, get on this rocketship before it's too late!"
- "Our exchange does $1B annually, so you know we're trustworthy!"
- "Hey investors, look at the massive demand for our GPUs (driven by the company we invested $100B)!"
Its generating the facade of activity, the same.
You are right theres no public ledger for the wash trading, but the fact that the underlying real physical asset is NVIDIAs product, lends the same intentional activity: to leverage apparent markeet activity to inflate the value of assets.
