I wouldn't lose any sleep over Bill Gates' predictions for Bitcoin. He might've been a software genius, but that doesn't mean he knows the future.

Remember, he was the guy who predicted, in the 90s, that the Internet wouldn't be a big deal (just as it was taking off). Microsoft had to play catch-up for years because he didn't think it'd happen.

So, carry on Bill, make your predictions - you obviously haven't learnt from history, so we'll add this one to your list of crazy quotes.

As for the other billionnaires who're so dismissive. You have to understand their positions. They're heavily invested in companies who stand to lose a LOT if they're displaced by cryptocurrencies. So of course they'll lash out if they see an opportunity to slow it down.

But these are smart people. They can say one thing, and do another. It's called hedging.
