Interesting.. They clearly say they cannot track for now oversea card payments (no real tools for that), and you can play 'easily' if you want to remit big money some years but cannot prove 'easily' it's a saving by spending less than 180days the year of the remit..
Too bad that no one seem in the crypto in this conference, would be interesting︀ to know if you hold stable coins (or even stocks/ETFs), if it's counting as saving︁ and not income, even if its not in a bank account for now..
