kFC feature exists

how ?
Devs use this kilo thing - kFC: 1 kFC = 1000 FC
When an exchange adds Futurecoin it's traded in kFC. So if 1 kFC is sold for 1 satoshi it means 1 FC is sold for 1/1000 satoshi.
Usually price can't be lower then 1 satoshi per coin, it's the minimum price for any cryptocurrency. Never before Futurecoin something was sold for lower than 1 satoshi. But Futurecoin with its kFC feature was selling for 1/10 satoshi per coin.
While true that a minimum coin price is one satoshi on a BTC exchange, the truism is meaningless. You have to have people wanting to buy at that price. What good is a "value" of 1 sat if nobody is willing to buy? I have seen coins go to one sat and shortly thereafter the buy order book dries up. GPUC and HEX are examples that come to mind. After that, they are only able to trade on other markets such as LTC, or get delisted entirely.
So, there is really no such thing as a 1 sat minimum price.
Also, I think that there is at least one exchange that trades in mBTC.
