Bitcoin is in a fire mode. The technical structure shows a tremendous positive shortterm momentum. Hourly support is located at 9000 (29/11/2017 low). Strong support stands very far at 2975 (22/08/2017 low). In the shortterm, the digital currency should continue rising at levels unseen so far.
In the long-term, the digital currency has had an exponential growth. There are decent likelihood that the asset will reach $40'000 in 2018.
