Warren Buffet may be a genius when it comes to buying, renovating, and selling property. He is good at these things and it has made him very rich.

It does not mean that he knows shit about technology, much less cryptocurrency.

I consider his opinion to be somewhat interesting (like watching a train wreck), but ultimately worthless.

I just spent a couple months in Kenya. I can see how popular M-Pesa is there. I was walking with my youngest wife and she said that she wanted a coke, so I mentioned that neither of us had brought no money. She said no problem, walked into the nearest store with an M-Pesa sign (there are a couple every block on the main streets), did something with her phone, and they handed her 500 shillings.

People in Kenya are already using electronic currency everywhere. My wife pays her electric bill with it. She sends money to her parents using it. Some of the buses even use it. My wife is even using her phone as a wallet.

Bitcoin will work so much better here (and the rest of Africa - everyone has a cell phone) in place of M-Pesa. It is the future.
