Bitcoin soared above $19,500 a coin on Coinbase's GDAX exchange around 11 a.m. ET Thursday, just three hours after it blew past $16,000.

The massive tear upwards seems to have put pressure on Coinbase's infrastructure, with the exchange saying on Twitter that users were experiencing issues logging into their accounts because of record traffic. Some users trying to log in were met with a message reading "AN ERROR HAS OCCURED."
