none because they're either promises or not tested enough.
False, Monero and others CryptoNote-based coins have been providing untracable transactions since inception.
Currently, only CryptoNote coins have anonymity embedded to protocol level, unlike Darkcoin which must rely on centralized "masternodes" to mix transaction.
Bytecoin (BCN) because of CryptoNote tech, and fair distribution.
Bytecoin is far superior to Monero in every way. And once the GUI wallet is released, among other advances, it will replace Bitcoin as the universally accepted Crytocurrency.
Rumors are that fabled Satoshi Nakamoto is involved in the Bytecoin project to amend the flaws of his first child, Bitcoin.
http://bitcoinrewind.com/bytecoin-next-bitcoin/I agree that BCN is first CryptoNote coin, but the distribution cannot be called "fair". BCN was ninja launched in deep web and 80% of total supply was ninjamined by very few people. Monero is born to fix the distibution problem of BCN.
What if you're like myself, who trades and doesn't mine.
It's very easy for me to get high volumes of the coin.
