A new Signatum fork has been launched!
MAGNATUM coin is based on the new skunkhash algorithm which is more GPU-friendly than any other altcoin (reduced heat while hashing).
The coin has been launched yesterday. There are already hundreds of miners, so come quickly while the difficulty is still low.
