whats the block time, is the coin fast and how is the privacy?
Block time is 50 seconds and mixin (aka privacy) can be 3.
Fast and privacy are relative terms. If you compare BitcoinMono 50 seconds with Bitcoin 10 minutes, BitcoinMono is super fast. If you compare BitcoinMono with Mixin with Bitcoin no mixin, BitcoinMono is super privacy. However, if you compare it with other Cryptonote coins, it is different.
