What is the First Cryptocurrency(First digital money)?
The first cryptocurrency is bitcoin but it is not the first digital money or cash. The first digital money or cash emerged in 1990s but sad to say most of theme gone bankrupt. The only remaining digicash or digital cash is Paypal and is still alive until today.
Bitcoin is the first digital money that uses blockchain technology. Then we called those currencies who use the said technology as cryptocurrency.
I think that there is a company itself that is called digicash which I think is the first Digital currency as you said but cryptocurrency has never existed until bitcoin was established and introduced to the whole world, wherein, this is the only cryptocurrency that I have known to be the best and cannot be competed with.
A lot of coins has risen after bitcoin establishment and till now, not a single project that you find in this market has ever been able to take the place of bitcoin in the heart of people, so unlike the other first digital cash that failed, bitcoin as digital currency will never fail because it's fate has been sealed by its effectiveness, the strong attachment of it to people and the reward that also came along with it for those that believes in its usage.
