This is only true if there really is a USD for every USDT out there in the market. If it turns out to be a fake, the whole thing comes crashing down and becomes unpegged as soon as growth stops, i.e. as soon as we run out of "greater fools" to keep supplying sufficient inflow of USD for everyone that's trying to cash out.

And you are required to wait 3 months for verification.
So, sure, go ahead and do it "right now", subject to those caveats.
