I believe Warren Buffett is a non believer of Bitcoin because he doesn't know much about it, how it works, its advantages, its technology and how it actually help people change their lives financially. For those who have had their lives changed, his words and beliefs about bitcoin, won't matter at all.
This statement is very true. I think I read somewhere about an interview with him, he admitted not fully knowing the technology behind and/or fully understanding how bitcoin works. If I can find the link again, i will definitely post it up in here.
OP, either you are trying to advertise bad news to the crypto community or you are wasting your time reading about nonsense words from people who don't even believe or is a a part of the crypto world...
