Why Bitcoin is Volatile aka I Told You So

Every bitcoin badmouther is using the price crash to tell everyone how right they were. Not really unexpected.

Speculative price swings are largely irrelevant, and bitcoin has value as a service regardless of the current price.

Ripple is a petty scam. Please don't advertise that horse dung to HN, we are smarter than that. Ripple generated 10 billion coins, they call them XRP. Of course this amount and even XRP aren't mentioned on that page you linked, an obvious bait. Ripple started giving away millions to generate buzz and use, they've yet to even give away 10% though, and the idea is to create enough value that they can eventually dump all their "genesis" currency and reap the rewards. They recently started giving away a few thousand a day with their ComputingForGood campaign, a pittance to create buzz for their scamware. Mastercoin's done the same thing with no real benefits over Bitcoin itself. Seriously getting tired of these fiat fiascos. I guess creating derivative cryptocurrencies is the new version of the classic pyramid scheme. Some people call Bitcoin a pyramid scheme because of the speculative bubble, fair enough. But these currencies, Ripple and Mastercoin, are true pyramid schemes. Founders plan to get mega-rich based on the illicit adoption of their scamware.

I correctly called the peak at 1200 (although I did not think it would peak there twice), and I'm calling the bottom at 300. This article has a very poor opening:

Bitcoin is based on the idea that money gets its intrinsic value from its scarcity, which is a misconception since money gets its intrinsic value from the volume of transactions involving goods and services that use it

No, bitcoin is based on the idea that money gets its intrinsic value from its trust model. That's why it has advanced crypto-mathematics to establish verifability, and so forth. Now. Bitcoin promoters think that the scarcity can drive the value up to the point where it becomes widely adopted. Criticism of this model to spur adoption may be totally fair.

If you and your whole family live in the U.S. and you have a couple credit cards, a debit card, and a bank account, Bitcoin is going to seem pretty useless. For you, the US dollar does just fine.

But the rest of the world isn't like the U.S. I visited Latvia recently, and my bank refused to let me withdraw money. Florida is full of Cuban Americans who want to send money to Cuba. Many people are imprisoned. The world is full of borders that make moving money difficult.

Bitcoin's market cap is moving towards where it needs to be to float all of those transactions. Even if no one uses it to store value, and no one uses it to buy groceries, it is still immensely valuable just as a means to move value from one location to another. Even if no one holds Bitcoin for more than two weeks, it will still have a market cap far north of a billion dollars.

I'm cautious about your Latvia story - its sounds to me like the bike was worried about fraud. Thats pretty common - about half the times I go to the US, I have to ring up the bank and get the card unblocked.

That being said, there are countries attempting to control the flow of money. Argentina wants to enforce its price for the dollar. Cyprus wants to prevent everyone taking their money and running. and so on. However, most of these countries see attempts to circumvent their controls as illegal. I feel its unwise to get my hopes up about bitcoin for this sort of transaction for that reason.
