That's really cold, even though I'm not much of a bitcoin believer either. And actually, it seems he hasn't necessarily benefited yet, because he's going to hold on to his bitcoins for the future. I would urge him to sell, say, half of them, at the very least and put those in more conventional investments, for his kids' sakes.
He did mention the bitcoins are in a safe deposit box, and his kids are tech-savvy. With a paper wallet, instructions, and a proper will, they'll do just fine.
Volatile object speculation, crapshoot, recurring bubble, vehicle of money laundering. There are plenty of disses against Bitcoin that at least have some validity. I'm sure there's more. But save Ponzi Scheme for things that actually fit the description.
The only reason BTC price rises is because of hype and idiots buying into the hype. Once the hype dies (as it's dying now), you can experience the pleasure of bag-holding.
Why don't you all in BTC? You are free to laugh at me when it hits 1k again.
technically, if it really is a Ponzi scheme as you state then you're saying that bitcoins will ultimately be worth zero. But in that case, he hasn't actually sold his bitcoins yet, so he hasn't benefited from the Ponzi scheme.
