Bitcoin Exchanges Plagued by Liquidity Issues and Attacks

Dramatic Changes in Bitcoin Price Affect Liquidity

Yesterday was an extremely positive day for Bitcoin. Senator Tom Carper held a Senate Committee hearing to discuss the legal and business implications of Bitcoin’s ever-growing popularity.

Overall, the tone of the session was one of open-mindedness and desire to learn more about the digital currency. The representatives from FinCEN and the Attorney General explicitly stated that digital currency, in and of itself, is not illegal.

In response, Bitcoin’s price skyrocketed to over $900, a new all-time high. Bitcoin donned the front page of the Wall Street Journal this morning, was discussed on NPR, and made its way into every mainstream media outlet.

Then, the problems started. With increased interest and positive sentiment in Bitcoin came increased trading volume, and many trading platforms just could not handle the demand. And in response, the price of Bitcoin dropped back down to $500.

Liquidity Issues at Exchanges

Coinbase, a US-based startup, suddenly announced that it was hitting its normal buy limits and warned users that, while they could place orders, these orders would not be priced for up to 5 days. At Coinbase, investors cannot buy Bitcoin reliably. Note that Coinbase is not technically an exchange, but because of its ease-of-use and trustworthiness, many investors go to Coinbase to buy Bitcoin.

Coinbase Liquidity Buy Limits Bitcoin

Mt.Gox, a Japan-based exchange, continues to have USD withdrawal liquidity issues. At Mt.Gox, investors cannot sell Bitcoin reliably.

Bitstamp, a Slovenia-based exchange, was hit with a DDOS (denial of service) attack this morning and went down just when the price dropped and investors wanted to buy.

Coinsetter, a relatively new trading platform, does not yet allow wire transfers from US customers and has trade minimums of 1 BTC.

These liquidity issues are a symptom of the reality that it is still early days for Bitcoin and demand is growing incredibly fast. But the problems these exchanges have experienced also highlight the risk in being a currency speculator in Bitcoin. You may be able to buy low or sell high, but perhaps not both on the same day.

Note: Other exchanges exist that were not profiled, namely BTC China (now the largest Bitcoin exchange in the world), BTC-e, and others. Read our comparison of exchanges and Bitcoin wallets to learn more.

Bitcoin Breaks $270 in Historic Climb

Today marks a new all-time high for the digital currency Bitcoin. For the first time ever, Bitcoin was traded at $270 on Japan-based exchange Mt.Gox. On Coinbase, the price of Bitcoin was just below $270.

With nearly 12 million bitcoins in circulation, Bitcoin now has more than a $3 billion market capitalization

Here are the charts showing the historic climb of Bitcoin.

Looking Back at the Last Peak

The last time Bitcoin reached prices this high was in April 2013. The currency reached $266 and then crashed dramatically.

This time, there seems to be more stability around this climb. Increased adoption and trading volume in China has contributed to the price climb.

Bitcoin Cloud Wallets Comparison: Security and Liquidity

Like this? Share it.TwitterFacebookGoogle+LinkedInReddittumblrbufferEmail

This question originally appeared on Quora, and was answered by Will O’Brien, owner of On Bitcoin.

Q: Which site is best for keeping a cloud bitcoin account? Specifically I want to: 1) keep my balance secure, and 2) change in and out of USD easily.

Sadly, the answer is none of them at this time. But there are some exciting new companies on the horizon.

First, some background. You can hold your Bitcoins in a wallet (cloud or desktop), at an exchange, or in cold storage. Each has its own profile for security and liquidity.

Security: There is a trade-off. Wallets and exchanges that are easier to use are often less secure. This is not a rule, just the current state of affairs. The biggest risk to Bitcoin is theft. If someone gets your private key, you will be robbed. See Bitcoin Theft: Mt. Gox Attack Pillages Investor’s Bitcoin Account as an example of how a Java chat applet was used to pillage a Mt.Gox user’s account.

Liquidity: Many exchanges have difficult account creation (to ensure security) and a prolonged wait to exchange to/from BTC, both as a hedge on currency volatility and because other institutions have delays, e.g., bank transfers. There is also regulatory risk and perceived regulatory risk. For example, Tradehill recently suspended its exchange due to regulatory concerns, Mt.Gox froze USD withdrawals, and Dwolla cut off Bitcoin users.

Bitcoin Cloud Wallet Security Liquidity

The general rules of thumb for both security and liquidity are:

  1. Never keep a large amount of money in an single Bitcoin wallet. Some Bitcoiners would say a single wallet should be used only once and not hold more money than you would be comfortable losing in a theft.
  2. If you are amassing BTC as an investment rather than day trading or buying and spending, consider cold storage.
  3. Keep on top of your account security like you would at your bank. There will be new Bitcoin wallet services that do everything for you that BofA does today, but those are in the future, not the present.
  4. Keep on top of your service provider. If they get impacted by regulation or attacks, so will you.

With that in mind, below are the major players to consider.

Coinbase - SF-based Bitcoin wallet startup
Pros:

  • Probably the most user-friendly site available. It’s a simple, intuitive, web interface for buying and selling.
  • Uses ACH transfer for buying/selling from USD.
  • Real-time charts and exchange rates.
  • VC-backed and reputable amongst the competition.
  • Android app and iPhone app available.

Cons:

  • Account setup is not trivial. Requires adding a bank account, verifying phone number, installing 2-factor authentication, etc.
  • Transaction delays: BTC-to-BTC transactions take 1 hour to clear. BTC-to-USD and USD-to-BTC transaction take days.

Bitcoin Block Explorer – Blockchain.info - web and mobile Bitcoin wallet
Pros:

  • iPhone app!
  • You can buy BTC with SMS payments.

Cons:

  • Very techie user interface, not intuitive.
  • No services. Very basic buy/sell functionality.

Mt.Gox - Japan-based Bitcoin exchange
Pros:

  • In the early days, Mt.Gox had a large amount of volume and liquidity.
  • Still considered a leading exchange.

Cons:

CampBX Bitcoin Trading Platform - US-based Bitcoin trading platform
Pros:

  • Reviewed as better than Mt.Gox.
  • Based in USA.

Cons:

  • Delays in initial trading after placing funds.
  • May be impacted by Dwolla decision to cut off Bitcoin exchanges.

BitGo - Startup with promise of most secure wallet (note: this is a relatively new startup with interesting technology that is coming to market soon)
Pros:

  • Innovative security implementation enables most secure wallet.
  • User-friendly site, easy to execute transactions.
  • Best account creation flow.

Cons:

  • New to market.

Bitcoin Exchange Tradehill Suspends Trading Due to Regulation Concerns

Like this? Share it.TwitterFacebookGoogle+LinkedInReddittumblrbufferEmail

More Troubles for Bitcoin Exchange Tradehill

Tradehill is a US-based Bitcoin exchange that has grown in popularity as the chief competitor to Japan-based Mt. Gox. Tradehill has tried to position itself as an exchange for traders, especially those looking to move larger blocks of BTC.

Now the company has run into troubles, and has posted a bulletin on its site notifying users that it has suspended trading “due to banking and regulatory issues.”

Tradehill suspends Bitcoin trading

In February 2012, Tradehill shut down “due to increased regulation” and a dispute of $100,000 with one of its payment processors. CEO Jered Kenna posted the announcement on Bitcointalk. The company later bounced back from this issues and has been on the rise, until this latest suspension of business.

Below is the full bulletin from Tradehill. We have reached out to the company for further comment.

Many of you have come to know Tradehill as the digital currency exchange of choice over the last six months. We have appreciated your patronage and have delighted in providing a reliable service to help you reach deep liquidity in the Bitcoin market. We have recently made the decision to temporarily suspend trading on the Tradehill platform, due to banking and regulatory issues. This decision has not been made lightly and we regret having to take such action. However, we embrace the silver lining of our situation and plan to take this opportunity to upgrade, improve, and polish our trading platform.

Tradehill registered with FinCEN in August 2013 and is actively engaging with banks and regulators to continue development of future business products and practices.

We would like to thank our clients, current and past partners, supporters, and advocates for all their continued support. The Bitcoin space has proven to be an exciting and dynamic environment. We are proud to have the opportunity to be at the forefront of this new domain.

[Update 11:15AM PT: Tradehill shared with On Bitcoin the following details around their suspended trading]

The Internet Archive Federal Credit Union has experienced operational and regulatory issues and we are no longer able to continue our developing relationship. Both Tradehill and IAFCU were excited about this relationship and both regret this unfortunate outcome. Tradehill’s integration with IAFCU had allowed for clients to buy Bitcoin with a balance in an account with their own name. This allowed clients to trade Bitcoin with funds that were stored in a federally insured institution.

Our clients still have full access to their funds. We are consulting with regulators to define the most appropriate licensing strategy for our current and future business practices. We are also actively engaging with banks and regulators to continue development of best practices for Bitcoin regulation and compliance.

This is only a temporary suspension of trading. We are continuing with planned development of our trading platform, to provide an improved user experience, as well as additional planned products. We hope to resume trading operations soon.
