Wall Street can't wait to short bitcoin
The price of bitcoin is up more than 1,500% percent this year. Next week traders will get a way to bet the price goes down.
Why it matters: The average holder of bitcoin now are millennials, counter-culture folks and "other amateurs who are interested in the technology," said Ihor Dusaniwsky of financial analytics firm S3 Partners. New futures trading in bitcoin will open the market to professional traders.
