Unable to build a meaningful arbitrage cloud for NMC with USD as a base currency. Please select another coin or pick a different base currency. Namecoin s a cryptocurrency which also acts as an alternative, decentralized DNS, which would avoid domain name censorship by making a new top level domain outside of ICANN control. The coin is designed to halve every four years with the same cap limit as Bitcoin of 21,000,000. With the domain registry service a small number of NMC will be destroyed so after mining has finished there will still be a deflationary ellement in place. Namecoin was the first coin to switch to merged mining.. Namecoin is is one of many evolving digital currencies in which encryption is used to regulate the generation of units of currency and verify the transactions independently of a central authority. It is traded on 16 exchanges including BitSquare, Yobit, Poloniex, Cryptopia, BTER and Bleutrade in multiple currencies such as BTC, USD, CNY, RUR and othersETH.
