Trade with it till you lose it- no taxes, otherwise pay taxes on the gains you made up until 12/31 when tax season comes around.

Got it. But do you have to pay it in advance or for people with a w2 job, do they add extra withholding in their paychecks to account for any big gains? I guess is there any underpayment penalty or you just pay it all at year end?
