TD Ameritrade, one of the top three retail brokerages according to Tabb, is planning to let certain clients trade Cboe's bitcoin futures contract on Monday.
The brokerage will not initially support CME's bitcoin futures, which are set to launch on Sunday.
Interactive Brokers let clients trade the Cboe futures contract at launch and said Friday that it plans to let customers bet on and against the CME contract.
I think this is just the beginning of bitcoin and for the overall cryptocurrency market.
