Bitfinex is known to be scammy without any sort of audits. I would pay a premium to go buy a confirmed backed stable coin.
Here's the way I see this playing out: Tether resumes all services, for the near future, people start to see the reasoning behind audited USD stablecoins, they start switching and we move into the sideways/bull market.
IF Tether crashes and burns and bitfinex shuts down, we are all royally screwed, because 99% of the eco-system is based on Tether, it needs some time to wind down.
So at this point, time will tell but be extra careful. My hope is bitfinex avoids any serious issues, and gives time for the crypto community to transfer over to a audited stablecoin.
