Is Eth-coinpool legit?

Hey guys, just getting into the basic stock market but I had someone message me about mining. This is a term I've heard loosely tossed around but I honestly have no idea what it is. They suggested I use Eth-coinpool.com which when I look at the website it seems sketchy as I can only open it on my wallet app and the only link brings me to Ethereums main page?

Should I be concerned about this link? My guts telling me yes.
