Will BL3P support Litecoin or other altcoins in the near future?

Is BL3P licensed by the Dutch Central Bank?

No, Bitonic and BL3P have no license of the Dutch Central Bank (DNB). We have applied for a license as 'Payment Service Provider'. An official response from DNB shows that Bitonic does not require a license. Because Dutch banks do require a license, in our collaboration the structuring of Bitonic as a financial institution offers comfort towards the banks and users of BL3P. More information about the license application and our measures to be compliant can be found on our compliance page.

Verification process

Why do I need to verify before I can trade on BL3P?

If you want to buy (iDEAL) and sell (SEPA) bitcoins without an account or identity verification, we recommend to use

The email address related to your account can not be changed yet. However, you can add an additional email address on which you will receive notifications. This email address will be used to receive confirmations at login, withdrawals and changes to the security options. If you can't login because you no longer have access to your email address, please use this form.

Changes have been made to my business entity. How do I inform BL3P?

If the changes concerns authorized entities, stakeholders or an address, this information should be transmitted to BL3P directly. This can be done by making changes in our verification system.


When can I start trading?

Once your account is verified, you can start trading. From this moment it is possible to deposit money or bitcoins and to enter orders.

How fast is BL3P?

The trading engine that processes all orders from BL3P currently has a processing speed of roughly 1000 trades per second. This is more than sufficient for the time being. We are monitoring the amount continuously to let the engine scale with increasing activity.

What does it cost me to trade at BL3P?

BL3P charges a percentage of trading fee per order. To prevent spam transactions we charge a flat fee of 1 euro cent per (partially) executed order (regardless of the number of trades). In addition, there are costs for depositing or withdrawing euros and cryptocurrencies. For an overview of the current fees see the fees page.

How do I buy or sell bitcoins?

On the trading page you can buy or sell bitcoins through a market or limit order. For both types of orders you can choose to use euros or bitcoins as the base of your order. If you opt for euros, fill in how many euros you want to spend or receive. BL3P will then automatically calculate how many bitcoins you need to sell or receive to realize this amount in euros. It works the same way if you use bitcoins as the base: then BL3P will calculate the corresponding amount of euros.

What is the difference between a market order and a limit order?

The option market order is enabled by default. You buy or sell bitcoins based on the current demand and supply. If you choose this option, BL3P will automatically fill in the current market price. This price is an estimate, with a market order you risk that someone trades faster than you. Or a supply can be removed, which means you will trade for a less favorable price.

If you want to set the price at which you buy or sell bitcoins, choose a limit order. With a limit order you are able to set your required price for selling or buying bitcoins. The limit order is entered into the order book. It is therefore impossible to predict how long it will take before your order is executed.

How do I cancel an order?

On the trading page under 'open orders' you can view and cancel your current orders. Canceling your open orders is possible until the time of fulfillment.

Depositing and withdrawing

What payment methods do you accept?
The deposit of euros is currently possible with an iDEAL or a SEPA transfer. In the future, we would like to offer other payment methods, but at the moment these are the only methods that we consider safe enough and which do not provide the ability of

chargeback. This is important because bitcoin transactions are irreversible. Of course there is also the possibility to deposit bitcoins.

How long will it take for my deposit to be credited?

How long it takes to credit your deposit, depends on the payment method you use. Below an overview:

  • Bitcoin
    Most times within 30 minutes. After 3 network confirmations the bitcoins are credited to your account.
  • iDEAL payment
    Immediately after completingthe payment.
  • SEPA payment
    The processing speed of your SEPA payment depends on the bank to which you are connected to. The speed of the process also depends on whether the transaction is made within the Netherlands or internationally. Generally, the deposit will be credited to us within two working days, after which we will directly credit it to your balance.
Why is my payment not processed?

If your payment is not processed, there may be several reasons.

  • Bitcoin: You have not added enough miners' fee. If you added little or no fee it may take long before the transaction is confirmed and credited to your balance.
  • iDEAL: the payment failed because of a problem at the bank.
  • SEPA: the added description is not correct, the transfer will be reversed.
  • SEPA: your account has not been verified yet. The amount paid will be refunded if you didn't start verification process yet. If you have started the verification but it is not yet completed, the amount will be retained temporarily. After completing the verification the amount will be credited to your balance.
  • SEPA: you made the deposit to the wrong account number.
Are there costs for deposits and withdrawals?

Yes, we charge a fee for both withdrawals and deposits. For an overview of the current fees see the fees page.

When will I receive my withdrawn money ?

How fast you will receive your withdrawn money, depends on the payment method and size of the amount:

  • Bitcoin
    Bitcoin withdrawals are processed automatically as long as our hot wallet allows it. Withdrawals up to 100 bitcoins are normally not a problem. After business hours larger quantities sometimes have a delay up to several hours (even if you would split the withdrawal).
  • SEPA
    SEPA withdrawals are processed every day. The processing of your SEPA payment depends on the bank to which you are connected. The speed of the process also depends on whether the transaction is made within the Netherlands or internationally. Generally, the amount will be on your account within two working days. For Dutch bank accounts this is usually within one working day.
How much money can I deposit or withdraw in one day?

The daily limits for depositing and withdrawing euros and bitcoins can be found here.
