Is Crownstone good for investment?

No, Crownstone is risky due to its unlicensed status.

Although the broker is registered in St. Lucia as an International Business Company, this registration does not imply authorization from relevant financial authorities. More importantly, the Financial Services Regulatory Authority (FSRA) of St. Lucia has stated that forex trading activities are not licensed in the country. This means Crownstone's forex trading operations are not permitted.

In light of this, Crownstone seems to be operating in an unregulated environment, rendering its offerings highly risky. To protect their hard-earned money from potential fraud schemes, investors are strongly advised to stay away from unregulated brokers like Crownstone and instead choose fully regulated ones.
