I think a lot of the volume you see in these new coins is "artificial" and not coming from newbies. Buy coins with account #1 from account #2, Sell coins from account #1 to account #2, repeat as needed. This way new coins can achieve decent volume with the only cost being trading fees. Just a guess.
