You have all rights to move your bitcoins. Of course you can move your bitcoin anytime anywhere. There's no limit for bitcoins. About the fork it will not stay forever we all are ready to face it. It will end one day but remember if you do not move your bitcoin from the wallet, you can get free Bitcoin gold coin. So I think wise people are not cashing out bitcoins. They are buying more to gather more bitcoins so when fork happens they will be able to gather more free Swegit2 Bitcoin.
The Bitcoin gold coin was based on a snapshot two months ago and you can still get the coins even if you have since sold all your BTC coins
based on your balance on the day of the fork so i would expect that the revised Segwit2x fork taking place tomorrow to be just the same.
"Wise" people will not put up with slow speeds and mega high transactions fees regardless of the perks they receive along the
way and trust with the greedy miners has been broken so i suspect a lot of people will start voting with there feet myself.
