XC coins, along with the other alts, will be used as payment to the team developing and supporting the whole blocknet project. If some1 got real life expenses, he might sell XC to purchase btc/fiat. Some1 else might hold on to his XC and spend some other alt or btc, others might just accumulate as long term investment because he has other sources of income for real life. Dumping at its core meaning is really overused, and not rightfully so.
