UPDATE
My transfer I initiated Julyl 28, 2017 at around 6PM Central Time just now cleared July 30, 2017 at 12:40PM Central Time
If you still have Bitcoin on Coinbase and your wanting to get it off Coinbase your fucked. I know the title was a bit dramatic, don't worry your not going to lose your Bitcoins, but at this point if you were wanting to get them off the exchange to take advantage of Bitcoin Cash, at this point it's not likely to happen.
I have a Bitcoin transfer from Coinbase to my Trezor going on 38 hours that is still pending. I'm not blaming Coinbase or whining however as it's my own stupid fault for waiting til the last minute, and at the end of the day I think this whole Bitcoin Cash thing is going to be a lot to do about nothing. Futures started off at close to $600 and are now below $400. I think by the time August 1 rolls around it will be even lower and once people start dumping it will fall even further, I don't think your going to miss out on much by not having Bitcoin Cash.
I think this goes to show everyone who has been warning people don't keep your money on an exchange was right. Sure Coinbase isn't going to steal from you, but your not able to move and control your coins how you would like to and that is a bad thing. This goes to show everyone should either get a Hardware wallet like a Ledger or a Trezor or keep your coins on a Wallet like Electrum and not on an exchange.
This Trick May Allow You To Move Your Bitcoins Off Coinbase
I havn't personally tried this yet but it's just a thought I had. If anyone has Bitcoin on Coinbase I highly doubt a transfer is going to go through in time. While Coinbase still technically says make your move by 10am July 31, it's doubtful they will go through.
Here is an idea I had which may allow you to move your money off Coinbase. Here's what it is...
Move your Bitcoin over to GDAX which should go through instantly. Trade your Bitcoin for LItecoin and/or Ethereum. Then since Litecoin and Ethereum transfers don't seem to be delayed send them to Bittrex or Poloniex or Kracken, trade it back into Bitcoin and then move those Bitcoin somewhere.
Sure you'll lose a little money on exchange fees and trasnfers but I think you should be able to move your Bitcoin wherever you want to move it.
