Not exactly rich, but I mined a couple of million of them back in 2013-2014. Still have a million left (the rest were stolen by Paul Vernon in the Cryptsy heist). Probably cost me around a thousand pounds in electricity and hardware costs, before I decided it was no longer worth it as all the altcoins plummeted in value. I held onto them for years because it didn't seem worth selling them for nothing. Obviously, I'm now happy I did.
