Do you feel same way or not?
I for one feel skeptical about it ...
Credit cards are a form of crypto currency... so is what is in your bank account. Most people don't realize what a crypto currency is and think crap like "BitCoin" is a good investment. News flash it isn't while bank accounts are insured against losses by the government bit coin is not. Private crypto currencies have zero value and are a scam and many of these are being run up in price by billionaires who will then cash out and devalue them leaving the gullible stuck with a bunch of worthless ones and zeros in the cloud.
That crypto-currency will be the USD.
There are already hundreds of mediums of exchange including every currency and commodity.
I doubt that I'll be buying any additional types of ponzi pence apart from the ones I currently use.
To proffer pieces of polymer promises for goods and services is already sufficiently hilarious.
