Wyoming LLC + Puerto Rico bank for Forex investments - stay anonymous

Hi,
I apologise if this was answered before, I found a lot of pieces of information but I am not sure if they fit together to make one nice puzzle. Could you guys help me?
1. I am based in Australia, non-US citizen
2. I want to find a structure where I can invest into Forex via a broker without this becoming apparent/official/notified. I do not want to offer any services, just trade with one of the many brokers
3. Utilise the returns via a credit card - not necessarily for cash but mainly for everyday shopping etc (stuff is bloody expensive in OZ)

Profits are likely to be $500 - $2000 per month so not really big numbers.

Could you tell me if the below model is safe from detection/anonymous for my purpose:

So my idea so far is:
1. Wyoming LLC via a nominee/agent
2. Offshore (non-US, non-AUS based) broker
3. Puerto Rico bank account for the LLC with VISA/MC to syphon the profits - or Transferwise?
4. use credit card in supermarkets here or on travels etc, possibly for cash but that is nice to have

So my questions are:
- Is this a structure that is CRS/FATCA safe (for the time being) ?
- do I need a licence for this? I am not providing any services other than investing via a forex broker
- does it remain anonymous or do I get identified after the first year (tax return in US) and it all falls over because AUS authorities find out from IRS ?

Thanks - and sorry again if someone answered this before, I am happy to get pointers to find the right forum entries!!!

@MrJonesy Did you research several forex brokers to come up with this structure? I'd be interested to know what brokers accept which jurisdiction and their requirements. Have you looked into SimpleFX?

Actually it is different now after talking to a lawyer/offshore company service. It's going to be a Panama company with a Seychelles Foundation as single owner. More expensive than something simple but avoids me (totally legal) to pay tax on the world income until money is distributed to e.g. me or my kids or so. By that time the idea is to live in a jurisdiction where no tax is payable on world income... Doesn't work of course if you need the cashflow to pay for your expenses now, but that is covered by normal job.
