Tether can decide to blacklist

unlicensed IOUs.
This makes me wonder if the users ever thought about the long-term perspective. With exchanges, you often hear the advice to take your coins out because "not your keys, not your coins". Weirdly enough, that generic recommendation isn't applied to "stable" coins!
Who thinks Tether will still exist 10 years from now? Or 50 years? I bet the dollar will still be around, and Bitcoin too. I'm not so sure yet about the euro, but I'm pretty sure the current stable coins won't last 50 years.
