there've been many, digicash, ecash, egold, but the problem with every single one of them is they depended on a central figure to lord over it to keep it in check. they were all effectively entries on a ledger just like bank accounts or paypal accounts are.
bitcoin is the first that didn't require that which is why it's become such a huge deal. the predecessors central element went bankrupt or were shut down and that was that. that's impossible for bitcoin.
none of the forerunners were crypto currencies though.
Thank you for your good information.
There were too many virtual cash available to use for payments, remittances etc. since before and even today but the currency used is the same currency of the country under company circulation limit, unlike Bitcoin, I can't fully figure out where actually Bitcoin began, made, stored, circulate, going etc... right? This kind of information is beyond my knowledge and skills for now.
Thanks again.
