If you look at the history of bitcoin massive bull run then you can see that every three years cycle there is a massive bull run and 2011, 2014, 2017 are the examples of those to create ATH. 2017 was really exceptional. Next bull run we could see in 2020/21.

So for me bitcoin will stay in large range like 3500 to 9000 for next 2/3 years. This is otherwise a good opportunity to build positions in crypto space and wait for better luck in 2020.
