Primecoin XPM Information
Primecoin is a crypto currency with a difference. It uses a Proof of Work mining method based upon chains of prime numbers rather than more conventional POW algorithms such as SHA-256 as used by Bitcoin. This unique approach not only makes Primecoin increasingly more secure as time goes by, but also contributes to scientific progress, with Primecoin miners holding world records for the most prime numbers discovered! While not a highly regarded crypto currency by retailers or investors, Primecoin still enjoys a level of support in the crypto community, due mainly perhaps to its unique mining method.
