Although my experience is limited to the last couple months or so, I've only seen bad things happen to a coin on its initial listing on whattomine.  Eventually they are overcome, but a delay in the listing seems to be healthy for the coin.

What happens on initial listing is that you put the coin onto the radar of Joe Schmoe.  Joe Schmoe doesn't care about any given coin, he only cares about what can be made and sold within a day or two mining.  Initially the listing will have a positive effect on coin price, possibly a good sized one.  But now, because its profitable to mine, Joe is all over it.  Joe doesn't care what happens to the coins that he mines, they all hit the exchange.  Now most of the newly minted coins wind up on the exchange instead of in the wallets of people holding for the future ( masternodes etc. ).  The huge influx of coins on the exchange drives the price down to below that where it was listed.

Coins that have reached enough maturity can absorb the influx on the exchange from the day miners.  I am not sure XSH is there yet.

At the moment everything about this coin seems to be growing organically, at a healthy pace.  Now might not be the right time to shine the bright spotlight on it that whattomine will bring.
