On Thursday, as the Bitcoin price made record high after record high, spiking to somewhere between $16,000-19,500, it was one of the top stories across mainstream media outlets, never mind Reuters, Bloomberg and the FT.

However, what exactly was the all-time high for Bitcoin? Because of Bitcoin's growing "price gap", it depended where you looked. But a price gap of more than $3,000…really? Actually yes, as Bloomberg explains.

Bitcoin traded above $19,000 on Thursday, but you may have missed it. As it was reaching $19,500 just after 11 a.m. on the GDAX exchange, which is run by the popular bitcoin brokerage firm Coinbase, bitcoin was still stuck in the high $15,000's on other trading platforms. Similarly, most U.S. traders woke up on Thursday to news that bitcoin was above $15,000, unless they were following it on Bitfinex, where it didn't cross $15,000 until soon before 10 a.m.
