* Anyone with good knowledge of how Centralized tether is?

* Is tether built on Bitcoin?

* What is the implications of building a Centralized (Non-transparent) Cryptocurrency on Bitcoin or other decentralized cryptos?  Could be abused/over printed?

* Should non-transparent Cryptocurrencies be even allowed to exist without being regulated by humans (humans in this case are governments/constituted authorities)


I really don't know much about tether as I haven't found time to research it properly.
