Risk and Volatility
Bitcoin has volatility mainly due to the fact that there is a limited amount of coins and the demand for them increases by each passing day.
However, it is expected that the volatility will decrease as more time goes on.
As more businesses, medias, and trading centers begin to accept Bitcoin, its’ price will eventually settle down.
Currently, Bitcoin’s price bounces everyday mainly due to current events that are related to digital currencies.
Bitcoin is still at its infancy stage with incomplete features that are in development.
To make the digital currency more secure and accessible, new features, tools, and services are currently being developed.
Bitcoin has some growth to do before it comes to its full and final potential.
This is because Bitcoin is just starting out, and it needs to work out its problems just like how any currency in its beginning stage would need to.
