Bullgeko is know as a not a reliable broker
Quote
BullGeko seems to be advertising through fraudulent ads showing Elon Musk opening specialized platforms for the Australian and Canadian markets. Once clients signed up, they were pressured to invest more, and the account manager manipulated their trades so everything would look profitable and promising. Once big money was invested, these same account managers simply disappeared.
