is there any problem withdraw with coinbase ?

I would suggest you to withdraw bitcoin to your personal wallet first, and later send it to your coinbase address when you want to sell your coin.

In rather sad news, multiple users are reporting Coinbase account suspensions due to gambling activity:

http://www.reddit.com/r/Bitcoin/comments/2e2yxr/beware_coinbase_is_banning_accounts_that_play_on/

http://www.reddit.com/r/poker/comments/2dxuqw/be_careful_seals_users_coinbase_has_blocked_me/

so with that known, I'm no longer recommending Coinbase as an exchange and would encourage others to use extreme caution.

Whoa, coinbase is joing the USA federales in trying to oppress gambling? What's up with that?
