BOJ Gov Kuroda says major central banks cautious of issuing digital currencies

"Issujing digital currencies"??  What is he on about?

Facilitating electronic payment services is all that is required to replace cash

US DOJ has started an investigation into the Trading practices of BitCoin and other Digital currencies citing like of controls that currently exist for Trading Stocks, etc. I guess this is a forerunner to bringing them all onboard the existing exchanges for established Control, rather than to see startup exchanges take away their business.

Digital currenies would never replace real money cash.

look at the bitcoin chart for example it continues to fall. Dont think someone would risk their cash to buy strange currency that price has such a volatility.
