Coinbase Warns During Times of High Volatility, Access Could Become 'Unavailable' (cityam.com)

An anonymous reader quotes City AM: A leading bitcoin exchange has warned that customers may be unable to get their money out quickly in the event of a crash in the cryptocurrency's price. Writing in a blog post last week, Coinbase's co-founder and chief executive Brian Armstrong, said despite "sizeable and ongoing" increases in the firm's technical infrastructure and engineering staff, access to Coinbase services could become "degraded or unavailable during times of significant volatility or volume. This could result in the inability to buy or sell for period of time," he said.

Armstrong added that there would be restrictions on how much customers could sell, or sell limits, to "protect client accounts and assets"... Bitcoin's market capitalisation rose above $300 billion for the first time earlier this week when its price rocketed to an all-time high of just over $17,000. Many analysts have warned that bitcoin represents an unsustainable bubble, though no one is quite sure when it will burst.

Reasonable

I don't find the current Bitcoin valuation rooted in reality. Yes there is a real tangible value in Bitcoin as it can be used to purchase online items from retailers like Newegg, but that is getting more and more difficult. As seen in the Steam example, the success of Bitcoin as an investment instrument is damaging Bitcoin as a payment method. The current transaction times and rates are crazy high, and the dream of buying lattes with is no longer seems viable.

I still have a tiny amount of Bitcoin and a few other crypto coins, but don't plan to buy any more. The price just does not make sense.

Any kind of currency which requires a third party to take part in the transaction, and which the full value can't simple change hands without a processing fee simply isn't practical or viable.

What exactly do you think Visa/MasterCard/Amex/Discover do??? 2.9% of every transaction, plus $0.35 per swipe. The problem isn't paying a 3rd party to authenticate your transaction. The problem is that BTC only can handle a fraction of the transactions that credit card networks can. Low supply of authorized transactions per minute with high demand for them leads to high BTC fees.

Waiting to have your transaction complete and having the price change during the transaction is going to be the BTC's biggest hurdle, IMHO. Even things like SWIFT and Western Union have significant fees to move money, but you always know up front how much you're going to get when all is settled due to (comparatively) low volatility with traditional currencies (dollar, euro, yuan, etc.)

Perhaps the most important knowledge gained is that governments should not and cannot be allowed to control the means of exchange.

Have you been asleep these past 17 years? Did you not see the instability wrought by repealing the Glass-Steagle act? Have you an understanding of the effect such things such as insider trading laws in helping maintain a close semblance of a Free Market in Financial markets?

Are you aware in the 1800's where there was little or no regulation of the markets there were 16 collapses, depressions and panics. In a much smaller economy. Between 1873 and 1896, a period called "The Long Depression" there were 6 of them.

The S&L crisis only occurred after it was deregulation. It destroyed S&Ls, a major competitor of banks, and now they are going after credit unions.

Because it is unregulated when the crash comes the fat cats, the exchanges and insiders, will walk away with huge sums and everyone else gets screwed.

The only way to even approximate a Free Market, a level playing field highly efficient and unbiased, is through regulation. Free Market != unregulated market. Unregulated Market usually means a captured market. That is the problem of libertarianism.

Circuit Breakers

This is by 100% by design and is intentional.

Look at who backs Coinbase. By conveniently shutting down during a large price swing, they prevent a run on their capitalization which to me speaks volumes as to the quality of the bitcoin exchange.

I already took profits during its initial run-up. Yeah, I missed an opportunity from the freaking 8k to 15k run, but screw it. It's better to leave the casino with a wad of cash than be a basket holder.

I've had some crpyofanboys flame me in another community because I sold so long ago and who seem to think their coins will always be worth several thousand dollars. Here's hoping they make something out of the transaction.

The problem is that bitcoin blockchain transactions can take from 10 minutes to more than an hour. During a "normal" day, this does not matter so much, because an exchange will have roughly equal numbers of buyers and sellers and can clear transactions internally with just a ledger entry. But on volatile days, the number of buyers and sellers may be skewed, and since the price is fluctuating, the exchange cannot take the risk of internal clearing. So they have to buy or sell bitcoins on the blockchain ... which takes time.

This is not some conspiracy by Coinbase. This is just the way that Bitcoin works.

The "quality of the exchange" is defined also by their survivability. When Bitcoin crashes, it may well crash to zero and wipe out exchanges that are willing to pay out while the exchange-rate is on free-fall. Hence it is very debatable whether this is a sign of low quality. The other thing is that the BC network itself will likely become extremely slow to do transactions when the crash happens and will get even lower when people stop mining because they cannot recover the electricity cost of mining anymore. The first effect will be immediate, the second one may happen within hours. This is an extreme booster for the speed the crash will happen.

So getting out at 8k was the only sane thing. I would have done the same if I had any bitcoins.

used to be known as "bucketshop"

[mbkennel]

This setup, trading private ious on a private unregulated 'exchange' which is really a business of its own has a very long history. Known as a 'bucketshop'. And it is inevitably filled with scammers and fraud, because the company that runs it has a direct financial interest in giving you poor prices and execution slippage.

Been there for equities (now forbidden), retail foreign exchange (lots of ripoffs there), and now bitcoin.

When professionals trade in banks, they ask *multiple* market makers for two-way, buy and sell quotes. Two way is important so that the counterparty doesn't know ahead of time whether you want to buy or sell. Not true when you're on a computer platform which already has your position and clicks---so it can shade prices and spread and blow you away or margin call you during volatility, giving you worse prices than the real market and pocketing the difference.

Re:Coinbase's problem

" If the volatility is too high, their margins are not big enough to cover their losses."
Untrue. Market makers list a bid, ask and quantity. Transparent markets have multiple market makers, each listing a bid, ask and quantity.
Coinbase is acting more like listed securities, matching buyers and sellers, making money on the spread. A professional specialist profits immensely from volume (and the spread). Hence the more volatility, the better the profit for a listed market. The real problem is when there's disorder, insufficient resources to handle sell and buy orders, as Coinbase obviously lacks, no one knows the price.
