Not legal tender here. I would have to go to a broker, which are require to gather and send to the US all the info on me that the Post Office, Money wiring services and banks here are required to do. Same with diamonds. I can not even sell off stuff online without the sales being reported to the US, including all the info on the buyer too. We are all under suspicion of being money launderers and all transactions involving a US person are automatically shared with the US under FATCA and possibly the OECD’s CRS, if no US person is involved, just under the OECD’s CRS. It is already set up and in operation, though not completely as designed yet.
