If we compared with 2011 and 2012, we have to say Bitcoin is a huge success. But in this year there was a lot of up and down in Bitcoin.

We have gone from people essentially only holding/buying bitcoin for speculative purposes to having increasing number of people buying bitcoin to be able to spend it at stores/merchants.
What we need to see in the future is for businesses that accept bitcoin to start to pay their bills with bitcoin they receive from customers
