Why is this broker block the withdrawal more than once a day? It just doesn't seem right to me. Is this broker even legit?

Uniglobe Markets is merely a registered broker in the famous offshore jurisdiction, namely Saint Vincent and the Grenadines. Financial Services Authority of the St. Vincent and the Grenadines (SVG FSA) actually does not issue any licenses for forex trading or brokerage nor does it regulate, monitor, supervise or license international companies engaging in such activities. Therefore, we highly recommend exercising caution when dealing with brokers claiming to be registered in or regulated by SVG FSA as they are actually under no valid regulation.

We advised you to withdraw your balance as soon as possible. If you failed to perform successful withdrawal, you'd better report to your local authorities.
