Now, I transfer the bitcoin on the electrum to another wallet to use for sale before I wait on November 1st. I fear moving the bitcoin out of the electrum purse at the moment makes me not get bitcoin gold
At this time, I should use bitcoin or wait until November 1

I have a question :
Today, 25/10, BLOCK 491407 REACHED , I still hold the private key of the electrum to receive the bitcoin gold in November, if today I transfer bitcoin into cash or sell it then in November I get bitcoin gold or not ?

yes
bitcoin gold is still there or lost

People do not exactly answer the toppic question. They ask that after 25/10 we sell bitcoin for money. So in November we will still receive bitcoin gold or keep bitcoin until November

I reserved bitcoin to receive bitcoin gold, after October 25 I was able to transfer bitcoin to another place for normal use or continue to reserve bitcoin until I received bitcoin gold 11/2017.
