Can you blame any investor for turning to bitcoin? Not really when considering the alternatives. The markets are at present so manipulated by the central and commercial banks that one can just not trust what you see. Prices and or valuations are artificially inflated and or suppressed so you never really have any idea whether you should invest or not and once you do you can never be sure whether you just invested in the next bubble or not.
So for that reason I can see why bitcoin is so appealing as it sure is for me. If I have to pick a place to put my money now it would be bitcoin. I have always believed in gold as being THE place to store funds in times of uncertainty but this is fading as its just as manipulated but also as its still within reach of the central banks and governments.
Bitcoin for me, at this stage, is the only currency/commodity [name it what you want] which you can trust.
