So i have a few questions..
If ANON was needed so badly why did the dev's not submit the idea to the Bitcoin core dev's foundation etc ?
because btc is transparant by default, which is a big no no... cash should be anonymous by default (like monero)...
oh and also because monero is based on a different protocol (cryptonote)...
oh, and also because BTC is totally politicised, good luck on trying to implement anything new (cough blocksize cough)
best regards
