Unlike fiat currency, cryptocurrency cannot be debased by any government because it's not tied to any government.
I think it will make more valuable for cryptocurrency in the future.
It is a matter of time because blockchain technology is growing and in the near future it will hold the world and then everybody will use cryptocurrency for his daily needs. Till that time it is not possible for digital currency to take over but when governments realize the importance of blockchain and cryptocurrency they will legalize bitcoin and Altcoin.
Yeah all is about blockchain technology and bitcoin is backed by this technology. They want the whole world to use bitcoin as their legal and regular currency in the future and they will succeed because the world is turning towards digital currency and bitcoin will hold the market in the future. No doubt it will take long time but the future is of bitcoin.
