I could not find a chart online that tracked Coinbase throughout the day, only market exchanges like MtGox or BTC-E, so here is mine.
For other prices at other exchanges, head over to cryptocoincharts.info.
If you don’t have a Coinbase account, please consider signing up under my referral link. [We both get $5 worth of Bitcoin when you complete a buy or sell of at least $100!]
If my work has helped you, consider sending over some Bitcoin =)
■ There is data since September 2013.
■ The price that is tracked is after the fees.
■ Pick a smaller date range for faster loading.
