When I say ideal I mean:
- People cannot born them from blown air and some day they will not be able to earn from coinbase's rewards.
- Over time, it will still have value.
- It cannot be spoiled by human.
- It is decentralized, no one controls it.
- You can send/receive the currency really quickly.
These are some basics requirements for the
ideal currency. But I have a question. There are public and private keys out there. You can take anyone's public key and send him/her bitcoins. In the future, like 2100, you understand that technology is advancing. Those years I believe that brute forcing a private key will not be something impossible. Do you think that bitcoin will be spoiled by human in the future?
Should bitcoin use SHA512? Or something even stronger?
These are actually the ideas that makes up "Bitcoin" but if the question tackles a broader sense of ideal currency, I guess a broader answer would mean a cashless way to provide payments.
I actually support you that idea since Bitcoin would really need a better service if it wants to be usable anywhere in the world. Bitcoin can still be controlled though??? but lets just wait it out on time
