No, because it is volatile unlike conventional currency which has a far more stable market value.
But they aren't totally stable. Atleast with bitcoin there's a possibility of my funds appreciating if I hold onto my investment but that can't be said about most conventional currency. The dollar keep making other currency looks useless. Five years back $100 was barely N20,000 ,in my local currency Naira but currently you can exchange same amount for as high as N50, 000. The fiat system is a fraud that only benefit the elites (bankers and government).
There's more advantage to using Bitcoin than conventional currency, for a start the other isn't digitalize and decentralized as Bitcoin is. The transaction speed is way above that of conventional currency and there's no restriction for international transaction like there's with the banks etc.
