Trinity Capital is not a regulated or licensed broker for traders even though it states offers that look good to be true.

Trinity Capital claims to be a licensed Investment Firm regulated by the Financial Services Authority of St Vincent & The Grenadines (SVG FSA) with Registration number: 450 LLC 2020. We indeed found a match result to this broker in SVG FSA. But please be informed that SVG FSA is not a forex regulator that issues licenses for forex brokers or regulates entities engaging in forex.

More importantly, the Portuguese Securities Market Commission (CMVM) issued a warning against Trinity Capital LLC for not being authorized to carry out any type of financial intermediation activity in Portugal, under Article 295(1)(a) and (b) of the Portuguese Securities Code. You can check the full warning from here.

The truth is, Trinity Capital is not overseen by any regulators. That means your personal data or your funds in this broker are unsafe and cannot be protected by any law. We would recommend traders stay away from unregulated brokers like Trinity Capital and trade with licensed brokers.
