Sounds like the options are…
- Wait for CTFC to drop the hammer on the remaining reputable brokers on their RED hit list
- Painstakingly hunt down your own business banking solutions globally (accepts US citizen beneficial owner, USD/EUR correspondent banking + FX broker money transfers) with backup accounts opened just in case
- bitcoin denoted FX accounts
- non US citizen/resident nominee director & signatory on broker & bank accounts (correspondent banking + FX broker money transfers)
- renounce US citizenship, pay your exit fee, back taxes and move out the country
- eventually give in and trade with Gain (bucket shop operator with multiple fines), Oanda (news release spread manipulator) or CME (<30:1 leverage & expensive real time data fees).
