Some of the limitations that cryptocurrencies presently face such as the fact that ones digital fortune can be erased by a computer crash, or that a virtual vault may be ransacked by a hacker may be overcome in time through technological advances. While the number of merchants who accept cryptocurrencies has steadily increased, they are still very much in the minority. For cryptocurrencies to become more widely used, they have to first gain widespread acceptance among consumers.
There is little doubt that as the leading cryptocurrency at present, Bitcoins success (or lack thereof) in dealing with the challenges it faces may determine the fortunes of other cryptocurrencies in the years ahead.
