Bitcoin has broken through $63,000, hitting a local high of around $63,400 before falling back to $62,700, still up 4% in the last 24 hours.

- Bitcoin has outperformed other leading cryptocurrencies, which have posted only modest gains.

- One reason for the rally could be the postponement of Mt. Gox's payout from October 31, 2024, to October 31, 2025.

- Another reason is China's announcement of a fiscal stimulus package to support the economy.
