When asked if IB was considering allowing bitcoin trading , he said no, not until he US Govt allows you to pay your taxes with it.
He's worth 1000x what every poster here put together is worth , and trades anything and everything on TWS, but not BTC.
Wonder why?
If you are going to quote someone, quote Jamie Dimon, Michael Novogratz or someone who either has good knowledge of the space or just trading and investment management in general. Peterfly built a good brokerage company worth 20B and thats great, As far as investing or understanding anything about trading or asset management, not sure I would listen to him. They lost Timberhill while waiting for a vix spike for the past 5 years, preaching about it to everyone and did make all sorts of odd business decisions. He has a good brokerage because of low fees and access to markets, that means he knows how to run a business, not how to trade, its not a hedge-fund, not an investment bank or even a payment system processor. I am not promoting bitcoin here, just saying what Peterfly thinks about it, is completely irrelevant. I would watch what JPMorgan, Goldman, Citi and other banks are doing with investments into block-chain and advising on bitcoin and also how much of the hedge-fund capital is flowing into the crypto markets, thats the real indicator of what institutional capital thinks of bitcoin.
As far as allowing for bitcoin to trade, they can't really do that, its not listed anywhere, if it gets listed as an etf or futures contract or index options will be allowed, then they'll have an option of allowing it to trade. Ib is simply providing an ability to trade on registered exchanges. Its not like if you want to trade gold you show up with 2 bricks at their headquarters and get cash

you trade futures or an etf. So the question kind of does not make sense and so he gave the "haha bitcoin whatever" answer, I think what he meant to say is: once it is properly regulated, listed, taxed then you will see it on our system.
