I don't know if it's a security as per SEC, but it is definitely a financial product such as a CD or a bond. The CEO confirmed this in his usual non-committal way when someone suggested that on HT. Nothing to do with hardware/software, just like your bank deposit is not about hardware/software.
A bond is a security.
A CD is a bank deposit regulated even more than a security. I think GAW would be better off staking it as a security versus a bank deposit.
Doesn't matter. According to the TOS Paycoin has no value and staking will guarantee you exactly zero coins! LOL!
