that is the main reason why shitcoins such as ripple (100% premine) and ethereum (72 million premine) inflated their market cap with fake (out of circulation) supply. to remain on top of the list that is sorted using the arbitrary and very wrong value known as market capitalization.

that means newcomers see it on "top" and think it is "famous" and a "good investment" so they start buying it up. so far it seems to have worked for them nicely but i don't think things would continue this way for long. after all the "top 10" altcoin list has changed significantly over the course of the market existence multiple times already.
