What large scale ponzi schemes existed in Eve? The only big money making schemes were casinos and betting sites.
Oh now I understand your question. It’s totally in-game legal to run a ponzi scheme in Eve but no one actually gets prosecuted for it.

Also, the name of the company was hilarious.
The claim that Plex isn’t allowed to be traded for real money seems irrelevant since there is nothing in the bitcoin spec that allows trading for real money either.
