For some years that I have spent in this industry, if I don't understand anything, at least I have tried to understand that every movement bitcoin makes, be it positive or negative must be attributed to some kind of fundamentals. In this industry, we believe that market does not just move upwards or downwards without actions. So, since we believe that the movement of Bitcoin is a reaction to something in the society, every movement that bitcoin makes, we will try to attribute it to something concurrently happening in that time. If there is no current event happening, we will have to manufacture one and name it as the cause of the Bitcoin movement.
If not what I have said above, I don't see any correlation between an assassination attempt and pump of BTC price.
