Absolutely fabulous. Now we can have the greatness of anon coins such as Dash and Monero into a single decentralized platform. This is really good news. If Ethereum could keep up with this, we will be able to see it go to the moon! Time to buy some more.
TIL there exist ETH Maximalist Monopolist Supremacists.
Single platforms are not "absolutely fabulous." They are single points of failure and should be avoided in favor of resilient heterogeneous ecosystems.
This feature is more like Dash than Monero, because the (ad hoc) anonymization is not done to all coins at the protocol level.
