Cryptocurrency is well known for being an extremely volatile and unstable asset. One of Its biggest problems right now is that it can’t reliably be used as a currency. It’s much more useful as a speculative investment than a means of transacting.
The space is so new and so unregulated that the market is sensitive to many different market pressures and individual actors. However, more than just being an annoying problem, volatility stands in the way of cryptocurrency’s mission of empowering people with the ability to transact directly, without third party intermediaries.
