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.
Precisely my thought but it wont be bitcoin but a new coin will be going through that cycle :). I have my hopes with REBL :).
Third generations coin will be key for taking the cryptocurrency forward, that is true but for that phase to happen bitcoin has to be in an age of adult . I still consider bitcoin as a kid because the mass adoption is still there to be achieved. Once that milestone we have in place then the boat will be driven by 3rd generations coins.
