For speculators, almost the same that bitcoin: it's $0 now, but it will be $97 later.
If I understand it correctly, freicoin will lose value while you hold it, and will provide incentive to give it to someone else (like merchants). Why would speculators, the first people to exchange real money into this experimental money, expect their freicoin to be worth more in the future, if this money is by design supposed to lose value? And isn't them holding currency that appreciates in value the root of your "money interest from holding money" problem?
