Bitcoin Dela in natečaji

You can earn money at Freelancer.com by using your bitcoin skills.

Bitcoin is a crypto currency, with the creation and the transfer of the bitcoins being based on a protocol that does not depend on the central authority. The coins can be transferred through computers or through smartphones and related devices, without the necessity of having a financial institution as an intermediate. This concept was established by Satoshi Nakamoto in 2008 and it was geared towards the world of electronic cash systems. If you understand more about this topic on a professional level, then you have a better chance to enjoy the advantages of being a freelancer at Freelancer.com.
