After more than a dozen years, the Bitcoin protocol has not experienced any successful attack. While service providers and individuals have been targeted, the software itself has continued to operate without any known exploitation or manipulation taking place. Bitcoin’s distributed nature ensures that all participants maintain consensus across the network and there is no single point of failure.
As with many early stage technological innovations, bitcoin’s price is subject to speculation and market volatility. It is no secret that the price of BTC has shifted dramatically in short periods of time, especially compared to more mature asset classes.
