KMD will also effectively be worth what BTC is worth across the ICO. If you invested BTC at $700 you still hold that value. Live coins can fluctuate and once KMD is live it will match the invested worth of KMD to BitCoin. Would you sell your KMD you got with BitCoin for Half? No! So neither would anyone else lol...
Well the market will determine the value of KMD and it could be much higher or lower than ICO price. I'm betting it to be higher, but time will tell.
