A currency that is guaranteed to be used and protected by a country, while also carrying value in almost every country will always be more stable and secure than a crypto that is built up by the daily opinion changing collective mind of some citizens. There's a reason we don't buy groceries with csgo skins. Even if you had a $1000 knife it's only valuable if people consider it to still be worth that price. Doesn't matter whether or not someone likes the dollar, the value won't change. Building a society with an ever changing currency would be disastrous. One day you'd be paying your employees $15 and the next that amount would be worth $37 but then the day after it could drop to $5. They would still have to go back to the dollar in order to adjust prices. If bitcoin and other cryptos value are still reliant on dollars its not good or stable.
