Bitcoin allows money to be sent anonymously across a peer-to-peer global network, with no intermediaries needed to validate or process transactions. That has made it attractive to those who want to keep their identity secret, including those buying and selling illegal goods and services on the internet.
Now I mainly work with BTC, taking into account its undoubted advantages for the market and participants. Including I highlight the reliability and regular appreciation of coins, the ability to quickly and cheaply conduct transactions, the lack of any documents, the complete freedom of anonymous actions.
