The future will catch up with fiat currency when people will appreciate digital currency such as bitcoin more than the fiat currency we have around. I believe digital currency and fiat currency can coexist in any economy in the world.
That is right, we have a great future of both fiat and crypto especially the Bitcoin which are great though the value of Bitcoin is more than that of fiat but we are observing the existence of both fiat and Bitcoin in many countries especially in European countries. Fiat help us out which is not hidden from us while the Bitcoin has shown its greatness in this short time.
Bitcoin will be a good substitute in payments terms especially if cash weren't available on us in a specific time. Its good to see that bitcoin is being know by many establishments now that it gains many uses at all.
