Digitalcoin was started May 2013, no premine or instamine, decent distribution since PoW rewards are kept long term. Recently changed rewards to 5 coins every 40 seconds, ~18m in circulation right now. We're open to changing the parameters whenever people want, we reduced the mint rate in an effort to stabilize market price and attract investor interest. We also added SHA256 and x11 hashing algorithms along with scrypt after Myriadcoin developed multiple algorithm hashing.
