Hey there's no doubt Mr Buffet is worth lot of money, has a huge amount of experience when it comes to stock market, but when it comes to technology he has zero experience. In his own words he won't invest in a business he can't understand, does this make the business bad, no it only shows his inability to see the bigger picture. Also it's pertinent to note that prior to this bloodbath, bitcoins prices have gone down many times only to bounce back, so don't let your fears guide you just hodl for the long term, all will be good.
