which broker should I use to automate trading bitcoin?

the broker should have low commission, be reliable and safe for the bitcoin.

 

Trade the futures through the IB api.

 

i mean real bitcoin, not future.

 

I think you should educate yourself first. There are no brokers for bitcoin. Its all direct access

 

so which broker meets my requirement? ie, safe, reliable, low commission, fast transaction ?
