Re: Frozen by Tether
"Trivial to remotely freeze."
That describes Tether, but does not describe most other cryptocurrencies. You should investigate how Tether works--it's very different from most other ones and there's a lot to complain about in it. Some of your points are intrinsic to most existing cryptocurrencies, whereas others are remediated by design decisions. As I'm not really an adherent, my defense will stop there.
