Informative article well done. I might only add that it might be worth mentioning how Safecoin is different to bitcoin and how that may affect it’s usability as a bitcoin replacement. Mainly Safecoin divisibility as was discussed (on and off with some off topic discussion) here and here.
I think a few people see Safe-“coin” just assume it is an alt-coin that follows Bitcoin divisibility standards, but AFAIK that is probably not the case so worth a mention.
