I think the main problem with myriad coin is there is just too damn many of them, the market is saturated with I think over 60 million coins now and it's only a month old? Hardly bears well for creating a scarce crypto currency to sit alongside Bitcoin. It may be fun for miners but what is the practical use for consumers, why should they want to exchange it for goods or services?
The actual quantity is irrelevant when it'd digital and divisible.
It's relevant when there is no illusion of scarcity. Also why should consumers care if the coin is good for miners, people forget crypto is designed to be used as a currency, not a plaything or science project for miners, do you imagine the average person who knows nothing of SHS-256, Scrypt or CPU vs GPU mining wanting to use Myriad? I respect technical innovation but it still has to serve an end use at the end of the day.
