CFD Market Moves from Mt.Gox to

Note that Plus500 have moved their Bitcoin market from Mt.Gox to

This is not surprising given the well documented problems on the Mt.Gox platform e.g. see some of our updates below.

Although we aren’t always in awe of the Plus500 service, this seems to be a sensible move; both the futures companies and individual investors need reliable underlying markets.

Some Bitcoin Exchanges Burst More than Others

BTC was trading at around the $920 level on the Mt.Gox exchange when the withdrawal problems started to be even worse than usual (see the 5, 10 and 11 Feb comments below).

At the moment, the Mt.Gox price is trading at $250.25, its lowest level since 6 Nov 2013.

With investors struggling to get out of the currency, we can see the problems are not just related to Mt.Gox. As the table below shows, there is certainly pressure on prices elsewhere.


5-Feb-14 Price
Price Fall
Mt.Gox $250.25 $920 $670
Bitstamp $626.02 $800 $174
BTC-e $599.79 $795 $195
Huobi $632.04 $815 $183

Given that Mt.Gox has #historically’ traded at a premium to other exchanges, the price fall on the Japanese exchange shows it has been hit far harder than some of the other exchanges.

Problem with the Software?

As reported below on 11 Feb, Mt.Gox said there was a problem with the Bitcoin software.

OK, maybe that’s true.

But if it’s a generic problem with the Bitcoin software why are prices on the other exchanges now trading at a $350 premium?

Bitstamp Suspends Withdrawals

Bitstamp, the Slovenian exchange, suspended withdrawals on 12 Feb after a denial of service (DDoS) attack.

However, a DDoS attack is often employed by blackmailers and is designed to stop a website from working by flooding it with data requests.

To me, the Bitstamp DDoS attack and the Mt.Gox #software issue’ are two seemingly different problems (or excuses).

Even if they are related, they simply highlight the high risks associated with #Bitcoin investing’.

Why Mt.Gox Exchange Has Stopped Bitcoin Withdrawals

Following on from the comments below on 5 and 10 Feb, Mt.Gox has stopped letting clients withdraw any money.

Serious Technical Flaw

It seems as though there is a serious technical flaw. According to Mt.Gox the non-technical explanation is:

“A bug in the bitcoin software makes it possible for someone to use the Bitcoin network to alter transaction details to make it seem like a sending of bitcoins to a bitcoin wallet did not occur when in fact it did occur.

“Since the transaction appears as if it has not proceeded correctly, the bitcoins may be resent. MtGox is working with the Bitcoin core development team and others to mitigate this issue.”

They may have rushed their press release given the title-case and lower-case spelling of Bitcoin.

Hopefully they do a better job of fixing the code.

$38m in ‘Missing’ Withdrawals from MtGox

MtGox, one of the largest and best known Bitcoin exchanges is reportedly having problems paying out to clients.

There seems to have been a perennial problem for users withdrawing funds from many exchanges and now, according to a new article, MtGox owes $38m in withdrawals that have not been executed.

Note that the author of the article clarifies that he could be biased because he’s waiting for a large amount of money himself.

Having said that, he’s basing his report on MtGox’s own data.

In short, over the last week, clients withdrawing money from MtGox have seen their funds debited from their Bitcoin account but have not actually received the money in their bank accounts.

This means that the exchange has “racked up over $38m in such unfulfilled withdrawals”.

MtGox have issued a statement saying “We’re working on it…[the problem applies] primarily to large transactions”.

BoA are now issuing guidance on BTC and David Woo, Currency Strategist, stated:

“Is Bitcoin a bubble? Assuming Bitcoin becomes:

(1) A major player in both ecommerce and money transfer, and
(2) A significant store of value with a reputation close to silver

“Then, our fair value analysis implies a maximum market capitalisation of Bitcoin of $15bn, or 1฿ = $1,300.

China Bans Bitcoin ‘Handling’

Bitcoin took a double hit today:
  1. China has banned financial institutions from ‘handling’ bitcoins
  2. Former Federal Reserve Chairman, Alan Greenspan, has said that “Bitcoin is a bubble waiting to burst”
For once BTC was having a quiet morning and then it sank from $1,214 to $899 in about two hours.

Investors should note however that the digital currency recouped a good portion of its losses and is trading back up at around $1,068.

The comment from Alan Greenspan carries some weight, but he’s not said anything that a lot of other commentators haven’t already said.

The China ban could have a far bigger impact; it’s surprising the Bitcoin market has been so resistant.

Of course, it is possible that, even though the news has been out for most of the trading day, it hasn’t reached enough people to hurt the market.

We could well see more selling over the next 24 hours, i.e. when China has a full day of trading.

As always, caution is required with this very volatile market.

Bitcoin is currently trading at $869, still a little off last week’s all-time high of $896.

It’s a fairly sceptical read, maybe that’s why we like it. However, it does help to point out some of the pitfalls of the e-currency such as:
  • The fact that users seem to be hoarding the currency rather than spending it.

  • The bigger it gets, and the more notorious it gets, the greater the likelihood of increased regulation. With regulation, the digital currency quickly loses one of it’s major advantages.

Bitcoin Ponzi Scheme

Looks like a new first for the SEC, charging someone for a Bitcoin ponzi scheme.

The SEC alleges that Trendon T. Shavers, founder of Bitcoin Savings and Trust (BTCST), raised at least 700,000 Bitcoin in BTCST investments, i.e. more than $4.5m based on the average price of Bitcoin in 2011 and 2012 when the investments were made.

Shavers promised investors up to 7% weekly interest based on BTCST’s Bitcoin arbitrage activity, which supposedly included selling to people who wanted to buy Bitcoin ‘off the radar’.

According to the SEC allegations, “BTCST was a sham and a Ponzi scheme in which Shavers used Bitcoin from new investors to make purported interest payments and cover investor withdrawals…Shavers also diverted Bitcoins for day trading in his account on a Bitcoin currency exchange, and to pay his personal expenses”.

Andrew Calamari, Director of the SEC’s New York Regional Office said “Fraudsters are not beyond the reach of the SEC just because they use Bitcoin or another virtual currency to mislead investors and violate the federal securities laws.”

Full details can be found at BitCoin Ponzi scheme.

Bitcoin Spread Betting

Please note that Spreadex have currently suspended their Bitcoin market.

It was suspended in mid-November 2013 after the company reached their risk limits.

I am told by one of the Spreadex traders that they may re-open the market but they need clients to start closing their positions first.

So it sounds like a lot of investors are long and happy to wait for the market to go up.

And, whilst I haven’t been told the following, my guess is that this market won’t be available for quite some time. If they have had problems hedging their book, they could easily be nursing a black-eye and won’t be in a hurry to re-open the book.

Basic trading facts and charges of the suspended Spreadex Bitcoin spread betting market:

  • You cannot apply a stop loss to this market
  • You can go long (buy) and short (sell)
  • There is only a daily rolling market – if you roll a trade overnight the interest is charged at 5% + 1Month LIBOR
  • Minimum stake: 50p
  • Spread: 2.5% either side of the underlying market on the MtGox exchange
  • Margin: 50%, a £1 spread bet on Bitcoin price movements at around the £90 level would require a £45 deposit to trade
The big spread betting and CFD companies normally only close a market if:

  1. They are consistently losing money, and/or
  2. Clients aren’t trading the market much and the fees set by the relevant exchange get too high

About Bitcoin – Definitions, FAQs and Resources:


  • According to the Rise and Fall of Bitcoin article, Satoshi Nakamoto is the pseudonym for the unknown developer(s) who designed the original Bitcoin protocol in 2008
  • The Bitcoin network was launched in 2009
  • Bitcoin is defined as an “open source peer-to-peer electronic money and payment network”
  • Coins are entirely unique
  • Bitcoin is sometimes refered to as a ‘cryptocurrency’ because of the way cryptography is used to secure transactions
  • Because it is a decentralised digital currency, some internet users and businesses use it as a substitute for government-backed currencies
  • There is growing evidence showing that BTC transactions are traceable / not entirely anonymous
  • Also see the short video guide to Bitcoin below

Bitcoin’s Appeal

  • There is no central bank to control supply
  • Governments do not currently apply any tax
  • Bitcoin are created at a steady rate. 21m coins will be created in total and then the mining process will stop. This means there should be no monetary easing / quantitative easing of Bitcoin
  • In essence, the currency is viewed by some as ‘digital gold’ and, therefore as a potential inflation/devaluation hedge

Bitcoin Exchanges

  • MT.GOX – based in Japan, Mt.Gox calls itself “the world’s most established Bitcoin exchange” – a warning, as of early 2014, this exchange seems to be having a lot of problems, see comments above.
  • Bitstamp – a European based exchange
  • BTC-E – a popular Bulgarian based exchange which a number of spread betting and CFD firms also use for their Litecoin prices
  • Camp BX – a US based exchange which allows short selling and (high risk) margin trading
  • BTC China – the largest Chinese exchange

There are many other exchanges and a good number have “mysteriously disappeared along with their clients’ coins”. See our Bitcoin market news & analysis section above for updates on this scurrilous behaviour.

At the moment, it’s not uncommon to see a set of prices like this:

Different Prices on Bitcoin Exchanges

Note that the Mt.Gox price is often the highest.

Of course, with so many Bitcoin transactions, why are the prices so different? You might be saying to yourself, “If the markets are genuine then I should be able to make a profit through arb’ing the market”

In short, it seems as though it is more difficult to get your money out of the Mt.Gox exchange and therefore arbitrage opportunities are not so simple.
