BCN
You should replace BCN with XMR (in your portfolio too, if you have any). Please don't lump that scamcoin in with legitimate coins. It was instamined. Additionally, someone in the Monero community discovered a bug found in the implementation of RingCT which when exploited would allow an attacker to create arbitrary amounts of coins. This bug was was patfched, but not without being exploited first. There is no evidence that it was exploited in any other cryptonote currencies prior to being patched.
