Digital currency providers: the use of exchangers
170. The segmentation of services in digital currency business models makes it difficult to determine who
the provider of the payment service is and thus subject to regulation.
171. The following diagram illustrates the segmentation of services in a digital currency provider business
model, in which the actual payment is broken down into three separate steps, each carried out by a
different entity:
Figure 4. Digital Currency Provider Step 1: Funding of the customer account
Customer Mr. X pays an amount of real money to Exchanger A, who holds a certain amount of the digital currency.
In exchange for the money received, the exchanger transfers an equivalent amount from his digital currency
account to customer Mr. X´s digital currency account.
Step 2: Transfer of Digital currency
Customer Mr. X instructs the Digital Currency Provider to transfer a certain amount of digital currency to the Digital
Currency account of Customer Mrs. Y.
Step 3: Withdrawal of funds
Customer Mrs. Y transfers a certain amount of digital currency from her own Digital currency account to the Digital
Currency account of Exchanger B. In exchange for the digital currency received, the exchanger transfers an
equivalent amount of real money to Customer Mrs. Y.
