That doesn't make a lot of sense. There's a .5BTC buy order at Cryptsy right now, at 2555. But instead of filling all the lowest buy orders, you can also make a sell order. Yes, you can sell 1 BTC worth of KEY. No, most people don't leave 1 BTC sitting in a buy order.
If you want to sell 1BTC worth of KEY at 2555, you can sell half of it immediately right now and the rest would get bought this week.
the rest would get bought this week? The total volume for the past month is about 1BTC.. so I don't know how you work that out, and the month before that is about the same or less.
And what if there is more than 1 person selling at a time, you seem to be saying each person would have to wait a week to sell $250 worth, so lets hope everyone keeps buying at this fantastic volume, cos if anyone with $1000 worth decides to sell the whole market will be locked up for about 3-4 months.
Maybe keycoin devs (if there were any) should implement a que system where only one person can sell at a time.
I agree with your first sentence, "That doesn't make a lot of sense".
EDIT: oh wait, there was a $10 pump to 0.00003292 yesterday on bittrex, wow, forget everything I said, this coin is going places!!
