The Bitcoin system could contain unexploited flaws. As this is a fairly new system, if Bitcoins were adopted widely, and a flaw was found, it could give tremendous wealth to the exploiter at the expense of destroying the Bitcoin economy.

the first time I hear it on the internet in 2012.

The short answer is no one knows. Unless you can time travel, maybe. As the old saying goes—predictions are hard, especially about the future.

Yes, digital currency will replace paper money. If we are talking about the means to which we use currency, then yes, paper money will be replaced by digital currency. But I do not mean that something like Bitcoins will replace traditional currency. I am speaking of transactions that use something like a debit card or credit card.

I think the best part is that there are no boundaries to bitcoin or cryptocurrency. No exchange values and no third party interventions. Bitcoin provides seamless transactions across nations with a ledger being maintained at the backend.
