Surely it is up to those that didn't take bitcoin seriously and or those that said bitcoin will not hit $100k or $200k because weather they believed it or not it must hit $1m or
even above. Here is my proof>> according to a thread by fillipone I came across sometimes ago which talk about Giovanni Santostasi - The Bitcoin Power Law Theory
Although I can't really explain everything about the law but the law somehowe is working accordingly because bitcoin has pass different price stages from differ circle from $10. $100, $1000, $10000, now $100k next will be $1m if from $10 to $100k KS achieve what then will stop hating from reaching $1m $200k KS even least compeard to the future price.  Here is the image of the bitcoin power law theory. 

This is a rendition of the "bitcoin clock" using the Power Laws: the beautiful spiral well represents the soundness of the theory.
