Why will go over 20k this month?  It can go or will not go for months. So there are two options and not just one option that it will go over 20k really fast. There is a lot of hype lately. Specially when people falsely compare this year with 2017 instead of 2016.  In January 2017 Bitcoin reached old ATH, but then there was a correction only from May 2017 it start grow beyond that. I am not saying it will totally repeat as it was 4 years ago. But it is possible it will. Probably higher possibility than to expect that Bitcoin will go over 20k this month and never go below anymore.
