Bitfinex/Tether generates massive profits everyday. I don't think they will mess it up.
Bitfinex 24 hour fees on transfers & trades = $1,134,419,856 Interest on margin= $2,000,000/day at least!
Tether has huge volume like Ethereum. Unlike Fiat money, Tether does't need anything to back it up, neither gold, nor oil or anything else.
I like your comment, this is exactly what I think.
Especially, CEO of Bitfines is the same CEO of Tether and the same team leaders.
Once Bitfinex is growing everyday, I think will grow too :)
But we have to be careful.
