In Bitcoin transactions, do not use an intermediary, or without a bank. In addition, there is no commission or administrative fee for each transaction. Every buyer also does not need to give his real name. Bitcoin is also seen as a simple and inexpensive transaction, because the payments are not tied to a particular country and without regulation. Micro business actors are very fond of such transactions because there is no credit card fees. Some people just buy Bitcoin as an investment, and expect its value to increase in a certain time.
