Hello

I am a bit concern about this coming fork as I started investing on Bitcoin recently and I don't have many experience.

I have Coinbase and Bittrex account and Ledger Nano S.

What I want is having the same amount of B2X and BTC when the fork happens (Block 494,784) and be able to trade with both of them at the moment (or at least with BTC).

I don't really know whether this is possible or not as in Coinbase they will give you B2X but stop trading for a few hours... right?

Another option is to store BTC at Ledger Nano S what I think is better but not sure if they will give me B2X. If the answer is yes, will this be instantly?  

Finally, do you know if Bittrex will be an option for trading just after the fork? So I would move my BTC from Ledger to Bittrex?  Or it would be on stop as Coinbase? Do you know any other exchange where this would be possible?

Thank you so much!
