Money is Rothschild and Bitcoin is Satoshi Nakamoto...Bitcoin will be a future money and how about cash???will people use cash at future time???
Yes, in future,it will now bitcoin is not yet so very stable unlike cash, and it is not yet easy to replace it.
Money invented here first before bitcoin, so how come you think that money would lose to a newcomer technology? Even if you say in the future, we can't tell what is exactly going to happen in the future only we speculate because we have some visions.
