What will happen to MTGOX codes, will it become COINLAB codes ? or mtgox codes = coinlab codes?
Will USA users still be able to move their funds around services that use MTGOX Codes???
No, they will not.
Mt. Gox will no longer be issuing MTGUSD and MTGCAD redeemable codes beginning April 10, 2012. Other currencies (e.g., MTGEUR, MTGGBP, etc,) will still be issued, though nobody in the U.S. or Canada can have wallets with those currencies so effectively no redeemable codes in any currency are available to those in the U.S. or Canada.
