I think every year is repeated. And at the end of 2018 with new volumes will jump even higher than in 2017.
Yes everything repeats, but not every year. PUMP of bitcoins repeats and reaches new maximum values each time. I see this happening every two to three years. Today, the situation around the bitcoin and the other alcoins is completely different from the bitcoin rising from $ 250 to $ 1,100 in the past, there are many people and institutions involved in this virtual world. Personally, i think bitcoin will exceed the value of 2017, sometimes around 2019.
