If it's not cryptocurrency then are there other options?

In terms of technological application and advancement cryptocurrency is far superior than FIAT currency. But in terms of stability and inherent value FIAT currency is far superior than cryptocurrency because every fIAT was guaranteed by every state with a gold that deposited its own central banks. If FIAT wants to come up with crypto government should adopt the technology use by cryptocurrency and that is Blockchain.

When viewed in the future, it will happen because Cryptocurrency has helped many transactions more easily and quickly. in addition, the growth of enthusiasts to use Cryptocurrency is always increasing every year. can be seen with the growth of ICO projects when crypto prices down, it does not reduce investor interest to always find a place to invest and use Cryptocurrency. replacing real money, I think that makes no sense. Crypto is known for now as an investment.

Crypto is absolutely real money no doubt about that, and because certain English usesage are not placed appropriately, it tend to bring in misunderstanding but obviously, crypto is real money any day. If we take out time learn the definition of money we might get it clearer. Thank you

As I see it, cryptocurrency has a more transparent system and the reason why the government still rejects it is because the price is very easy to change, but cryptocurrency will still have a fiat exchange rate pair, because not all countries accept payments using crypto, but only allowed for investment
