Anybody watch Sharktank? Cuban is a pretty smart guy, if he thinks bitcoin will fail, he`s probably right.
He is obviously a smart guy, you don't get $6 million and then $6 billion on two different occasions being lucky. But he is dead wrong on bitcoins sadly. I would love to explain why to him.
I'll give him credit for building and selling his first company at a decent price. But the event that "made" him, that $6B buyout, was an immensely lucky gift from incompetent idiots at Yahoo who couldn't spot a bubble if it punched them in the face. Way more lucky than smart.
If he's such a genius forecaster, he would've bought BTC early on like the Winklevii did. Those two, unlike Cuban, actually can be categorized as people with a great predictive record, having correctly spotted the two most massive tech trends of the past decade at a very early stage.
Not that I mind his stance. We need stupid people to stay skeptical about Bitcoin, so that they will be there to buy down the road, when the price is much higher.
