Their value is made up by the people who buy and sell it

Outside of that closed circle, a bitcoin is a scam.

The Onion is becoming the last bastion of real journalism.

Biggest vulnerabilities are probably unwillingness to consider upgrades to deal with quantum computing threats and its structurally dwindling security budget (if there is a maximum number of bitcoins, much less money will be paid to miners in the future, greatly reducing the cost of attacking the network). Not like you can trust the market to be rational enough to actually factor this stuff into the price though.

Is bitcoin a currency?

@cyrano 😂 yeah, I knew it.

Oh we're doing this again. Rich people decide that BTC will crash, they sell, articles like this appear, it crashes, they buy, it goes up.

Why you guys are so keen to help them to do this is the part I don't understand.
