The advantages of bitcoin  include the following:
Commissions for bitcoin transfers are either very small compared to other currencies, or absent.
Bitcoin transfers are unlimited. It also does not matter the location of persons performing transactions with cryptocurrency. All you need is the internet.
A Bitcoin wallet is very easy to set up, and you don't even need to enter any personal information.
The reliability of the system is superior to any other system, in large part due to the fact that bitcoin cannot be counterfeited. Taxes are not levied on operations in bitcoins, because the cryptocurrency is not official.
