The old chain CardB was exploited and the developer swapped the coin to a new chain (to void all remaining exploited coins) literally in a few days and in less than a week paid Cryptobridge 0.5btc to list the new chain.

now MNO updated in the 2nd week. NEVER seen any coin developer team move this fast ! The fastest coin project team in east and west!

Invested in bunch a nodes and never regretted!
