Apparently mentioning Tulip Mania in a discussion of Bitcoin goes too far.
More disturbingly, it seems as though you can trade in markets since "before you were born" and yet be completely unfamiliar with obvious examples of market collapse.
Perhaps chess.com should consider renaming itself to chess-blockchain.com.

You could make a bit of money, except you'd be out $8000 USD from a week or so ago. And you'll use scads of electricity in the process.
