Great write up I'll for sure have a look at these - hadn't heard of Franko or Secure before (hard to keep up when there is new coins every day) will for sure look at these and see how much additional support they get in this thread!
Franko, SecureCoin and DigitalCoin have been around for some time now, they arrived on the scene before a lot of these recent additions, most of which appear to be created by a '$20 a go' create your own alt service.
SecureCoin is based on Quark which in turn is historically based on SIC (sifcoin) and others, importantly it just lacks Quarks massive instamine and general insanity regarding it's economy and ongoing mining rewards. Using the established Bitcoin distribution model of 7200 coins per day for the first 4 years is a well proven method of coin distribution to miners and appears to hold up quite well over time.
