Choices are dwindling, quickly. Financial regulators are warning institutions not to onboard unlicensed financial service providers. While you're enjoying a legal loophole in SVG, it means absolutely nothing when you want access to the financial systems. It's well known SVG doesn't license or require license to offer FX brokerage but you need to comply with the laws of where your customers are based.
Look at what other companies are doing and mirror that, while you still can.
Or get yourself a decent, sensible license. It's really not that hard. Look at Cyprus, Mauritius, Caymans, Bahamas. Or explore options for being a whitelabel of someone who does have a license.
