Untapped CPU Power...
On first glance this looks kinda shady for a pirate site to borrow visitors' CPU power to mine crypto-currency.
Then you realize that the revenue model for almost the entire internet is based on ad revenue, and crypto-currency mining with visitor CPU power could potentially change everything.
Most people don't strain their computers, they just surf the web and send messages. There's a tremendous amount of untapped CPU power that could be used to process transactions and run decentralized apps.
