Even treasuries are not risk free, nor are they unbounded. Tether is trying to play in the big league, I'm not certain what the rules are, but I'm pretty sure making 1%-2% annually on the float is a pretty good deal, and that might even be a conservative estimate. In addition you have to keep in mind that it is also about absolute numbers. No one invested these billions with them, no one is charging them some kind of relative rent. Every dollar is profit. If you could make 0.001% off storing 5 billion, that would still be an attractive business model.
