It seems that there have been a lot of people complaining about Bitfinex. It seems that Bitfinex has been using Theters to pump Bitcoin price. Now a lot of people is shouting this might be the next MTGOX.
What is your opinion on this one?
I'm not worried, I don't have money there. I've never used bitfinex mainly because it's a USD exchange and that's not my currency of choice.
I'm worried about USDT running fractional and blowing up into everyone's faces,
You have the right to be worried because it's going to happen sooner or later. A balloon can't keep expanding forever. A great example of this is Zimbabwe. In 50 years you're going to pay $100 for a pack of smokes.
