"Buffett also said he would steer clear of bitcoin. Buffett said the cryptocurrency is an effective payment system, but so is a check. The idea that bitcoin has some intrinsic value is just a joke.
If you could argue back, you could point out the intrinsic value of the us dollar is a joke as well, but it seems to work as method to store value and is the backbone of the US and much of the world's economy.
I really think there's no such thing as bad press for bitcoin. As long as people keep talking about it, people will eventually adopt it as time goes on -- when they realized it is still around and working as intended after all those years.
