He meant, why 'would' people dump their coins I suppose.
@Ontopic, Probably they're already in a profit, and wouldn't risk it anymore. You'll do the same in the future believe me.
Or simple they who dump the price are impatient.
Have earned enough profit and don't want to wait more.
I would never dump the price, only if i have no other choice.
Another thing, they are trading expert. One trading rule is don't wait too long for price increase, If you make profit even a little when you buy coins much lower then sell it then wait for the next chapter.
Well this hidden rule seems to be working.
Because i am still waiting for an order for a month now.
And the result is really little profit but the price has been increased to much which makes other alt coins exchange rate to go really down. (About -20%)
