Park them in overseas account. If your profit is more than a 100k monthly you can set up a shady company here and overseas (where your money is parked) and export goods to overseas. It could also be in the form of services/consultancy too. Charge the other party (overseas) kaw kaw (mark up the price). Then you can bring back a lot of money.

Then you can move on to tax avoidance (not evasion please).

Then later you can use this 'illegal' money to invest in legitimate businesses or park in bursa or unit trust.
