Bitcoin and blockchain technology use raise cybersecurity questions

In recent years, technology companies and even national governments have started focusing on the use of Bitcoin and cryptocurrencies. The main reasons why this is the case is not difficult to determine: Bitcoin has potentially huge valuations (the current exchange rate is somewhere roughly around 1 Bitcoin = $450 U.S.) and is increasing in popularity as a means of exchange. As a result, all signs point to a future in which blockchain, the public ledger that serves as a record of all Bitcoin transactions, will play a large part in monetary exchanges all over the globe.
