If a coin is listed on that site, it's too late to mine that. You need to move on and find new ones.
Lol ... Are you still waiting for that Lambo? Keep waiting. It's not coming. Not for you brother. Haha.
Actually he's right... You shouldn't be laughing at him as if you actually know what you're talkign about.
If you want to hit it big you have to find coins to mine before the masses drive up the difficulty. Most people look at what to mine, so once the coin is listed there difficulty goes way up.
It's hard to find new ones that are actually worth mining because most of the are crap and the ones that aren't have a lot of people on them early (like ETN), but finding new coins and mining early is a very viable strategy.
