Surely 11% of greater than $5k by March 19 comes off as pretty low odds..... thus a very conservative perspective.
Personally, off the top of my head, I would have placed the odds of greater than $5k higher than 11%, but on reflection, $5k is about a 40% price appreciation from our current price, so it is difficult to suggest really great odds to expect a 40% price appreciation in BTC in merely about 2 months - especially in this current climate.
By the way, I did input the website on the chart and was able to find it... So here is a link
