Wherever Bitcoin is moving whether down or up, analysts will always look for possible reasons behind. And they usually have the skill in leading us to believe that one or two things can have a great effect on Bitcoin's price. Any demand for Bitcoin will always have an effect but whether the effect can be significant then that is another story. Ransomware has been spiking and most probably this can go on for a long time as long as we will have people and organizations falling victims to this crime and paying for it. However, on my assessment, this may not be significant not unless maybe 1% of the whole population who are online can be victimized by ransomware and majority of them are buying Bitcoin to pay the fees demanded by hackers. Attributing to something evil and unnecessary may not be doing good to something like Bitcoin, in the same way we don't really say that scams are contributing a lot to making the economy grow.
