So Bitcoin is broken a hundred times, you should sell them all.
By the way, the exchange system is decentralized. You seem to have a different definition of central and decentral as everyone else here has.
And you are legitimizing theft, as all hardcore anarchists do. Theft is a crime which cannot be allowed in a civil society.
Centralized = Mintpal in this scenario. A central agency, a single point of failure trusted with a large amount of coin.
Decentralized = peer to peer trading.
Simple.
By trying to erase the theft you are protecting the system that makes thieving like this possible.
Is this the long term solution? Everytime there is a theft roll it back?
How many roll backs? Who decides? How the hell do we ever use this for a currency if thats gonna be the case?
If you roll back you make this happening again way more likely.
You make it inevitable. Making the next rollback inevitable.
By not rolling back you force to find another solution. This way we move forward. Not backward.
