As far as I know only 6 confirmations are required for a transaction to be considered practically irreversible. Is it different for coinbase (reward) transactions?
There is also concern that Bitcoin could be vulnerable to hackers. Mr Ahmad said that recently it lost almost 20% in value on fears it was being hacked.
Am I missing something or is the hacking part nonsense?
Forgive my ignorance but how does mixing achieve privacy? The blockchain is public, so you should be able to trace back ownership regardless of the number of addresses it's been through?
