cryptocurrency can not take the place of fiat currency. truth is total manipulation in crypto market is controled by Bank and different financial organizations. If you say no then my question, how could be XRP a hundred billion coin become 3$ when its actual high could be maximum 0.50$.

They try to prove XRP(non-mineable coin) more profitable then BTC. Cause bitcoin is mother currency and mineable . If they can control bitcoin then total market will be in their hand . End of 2017 what happened it was totally according to their plane and the succeed. Remember bank will not setup mining farm but they can take away all of your mineable coin.
