Bitcoins went ballistic. They are up 33.6% at $17,100. Three weeks ago when I made my first purchase they were at $7,200.

The following is a link to a bunch of exchanges. I trade at GDAX and find it to be very user friendly. I read where the CME is going to get their settlements from Gemini.

It is going to be interesting to see what happens when futures and options on Bitcoins begin trading.

Best wishes,
