How does it work? is a service that automatically trades between USD and Bitcoins. has a smart trading engine that, on the basis of financial analysis, determines automatically when to buy and sell.

To join the service you do not pay monthly fees or setup costs. What you do pay is a 20 % fee of the gain. So 80 % remains for yourself.

Financial Yield

The yearly yield of the trader is optimized by performing simulations with real historic trading data of Bitstamp (> 12 million trades). The yield of the trader depends strongly on the bitcoin market. When the price strongly fluctuates, the trader makes the best yield.

Here is an overview of Cryptotrader’s achieved yield over the past few years.

Where is my money?

The USD that are needed to buy bitcoins, and the bitcoin bought, always stay in your own account on a supported bitcoin exchange. We currently support Kraken and Bitstamp. Both are well-known Bitcoin exchanges with a good reputation for security. They have a good safety protection of user accounts using Two-Factor Authentication (2FA). Two-Factor Authentication makes it much more difficult for hackers to access your account.

It is important to note that cannot transfer your money or bitcoins. It can only trade on your behalf. The money in USD and bitcoins always stay in your account at the exchange. There is no money stored at

How can trade on behalf of me?

Once you have an account with one of the supported exchanges you can create an API key. With this key, once you give it to us, we can trade on behalf of you. This key has limited rights so that we can only trade and not transfer your money to another account.  In the section “Getting Started” is explained how to create a key and how to set the correct rights for it.

How does work?

Once you are registered at our service, you will get a mail with a link to the which you need to create your own password. Once logged in, you see in the top left on your screen the your unique trader ID and it’s status. The trader is paused since the total credits is 0. Before you can start, you need credits.

How to pay? works as a pre-paid model, comparable with call-minutes on a cell phone. You buy credits (25, 50, 100 or custom amount) and as soon as the amount of credits is positive your trader will start automatically. You can buy credits using iDeal, PayPal or Bitcoin.

As soon as the trader generates a profit, the credits (being 20 % of the gain) will be booked off your credit amount.

Example: Say you gain 10 USD then your credit account is reduced by 2 credits.

When the total amount of remaining credits is at 0 or below, the trader pauses. You will be notified by email that your credits are low. You need to buy credits. By pressing “Buy credits” you can buy new credits with bitcoins or iDeal (Dutch banks). As soon as the payment has been received the credits are added and the trader starts.

Tip: Make sure that you have enough credits so you do not miss out on a good buy / sell oppertunity.

Note: Bought credits are non refundable

Trader is started

Here an example of a trader that already has been running some time. There has been made a profit of 1900 USD and the person has more than 20 credits left. The trader is started.

Using the menu, you can choose between the following information pages:

  • Home
  • Pockets (overview of all unsold pockets)
  • Actions (overview of buy and sell actions in the last month)
  • Credits (overview of bough and deducted credits)


You will receive automatically an email when the trader buys or sells bitcoins for you. The email contains information how many bitcoins are bought or sold, the price paid or received and the profit made (when there was as sell). This way you keep informed on the actions of the trader.


The trader will buy automatically bitcoins when there is a good buy oppertunity. To reduce the risk, it will buy new bitcoins for 10% of the available USD budget. The trader can determine a good buying oppertunity but it can not predict the future. So it is important to not use the full USD budget, because a even better buying oppertunity can follow.

Every buy of bitcoins is stored in a so called pocket. On the pockets page you get an overview of all unsold pockets. You can see how many (amount) bitcoins are in each pocket, the price of bitcoin during the buy and the total amount of USD paid for the pocket. The fee paid to the bitcoin exchange for the transaction is also shown, this is typically 0.25% of the USD value of the pocket. In the column age you can see how long ago the pocket was bought.


On the actions page you get an overview of all buy and sell actions.


For each buy you can see the amount of bitcoins bought and for which price. The buy is stored in a so called pocket.


For each optimal sell opportunity the trader will check which pockets can be sold with enough profit margin. This is decided per pocket. When there is a sell, the overview will show the amount of bitcoins sold, for which price, and for which bitcoin price the pocket was previous bought for. It will also show the profit in USD and the profit margin. Both profit and profit margin are netto (cost of exchange fee is already subtracted).

Credit History

The credit history page show an overview of bought credits and the deducted credits when profit was made.

How does the trading engine work?

Below is an explanation how the automatic trading works. Be assured, you do not need to understand everything. Just keep in mind that the trading engine works fully automatic and buys and sell bitcoins on favorable moments. The trader will only sell bitcoins when it can make a profit. If no profit can be made, it will wait for the next opportunity.

Financial analyses

The trading engine uses a MACD analyses to determine a favorable moment to buy or sell bitcoins. See also the graph. As you can see a favorable buy opportunities match exactly a MACD crossing from negative to positive.  Favorable sell opportunities match MACD crossings from positive to negative. The engine has some additional rules which make sure that good buy and sell opportunities can be found. Sometimes you have a weak MACD crossing which is not a good buy or sell moment.


The trader buys bitcoins using US Dollars (USD). We use USD and not Euros because the Euro bitcoin market is too small with too little price fluctuations. Using a MACD analyses the trader can find favorable buy opportunities. However, the trader cannot predict the future and therefore does not know if an even better buy opportunity will follow. The spread the risk of a good buy moment the trader always buys with percentage of the available USD budget. This percentage is dynamic and depends on the market (see FAQ for more info). The buy is stored in a so called pocket. When there is a new favorable buy opportunity the trader will buy again with calculated percentage, only when the price is now lower than the lowest price we have in existing pockets. This ensures that not too many pockets are bought for the same price in a side-ways market


When there is a favorable sell opportunity the trader will check for each pocket if it can be sold with enough profit margin. The rule is that we want a minimum profit margin of at least 6%. However, we also want the pockets to be sold within 3 weeks. So the minimum profit margin requirement slowly drops (lineair) to 1% in 21 days. After 21 days the minimum profit margin requirement stays 1%.

With the help of many simulations with real historic Bitstamp trading data (> 12 million trades) the trading engine is optimized to maximize the profit made in 1 year.
