Bitcoin has finished the week at all-time highs, blasting through $US3,500

It has been another huge week for Bitcoin.

The cryptocurrency cruised through $US3,500 overnight, and a short time ago was trading at just over $US3,600, just off its highs of $US3,669.

Goldman Sachs technical strategists wrote in July that Bitcoin had the scope to reach $3,691, a level that seemed wild at the time.

After the cryptocurrency split at the start of this month, its blockchain network began implementing a software update called Segregated Witness, or SegWit, this week. It’s designed to increase transparency.
