I guess we could argue, "It's good news for our slightly more subtle fraud if the blatant, obvious fraud gets stamped out."
Let's be clear, here: There's a substantial difference between Bitfinex engaging in outright financial fraud vs a bunch of people buying into the value of a virtual currency for reasons no one can understand.
BTC is not a ponzi. It's just a long-running speculative bubble. A collective delusion. You can disagree with that, sure, but it's certainly no more a fraud than Beanie Babies or tulip bulbs.
BTC didn't get to the price it is today on the backs of a few cypherpunks experimenting with decentralized digital currency technology.
You've basically described commerce.
Pick a random asset class--stocks, real estate, commodities, etc--and ask yourself: are there people who are hyping that asset who have a vested financial interest in it?
The answer is almost certainly "yes" in every case.
I have honestly been surprised how long this obvious tether saga has gone on.
