Olivemarkets, the brokerage firm, has a serious security flaw: they have direct access to user credentials, and their infrastructure is unreliable. They used to arbitrarily cancel bonuses I got through trading. I sought the closure of my account and ended my relationship with the company since I was fed up with these concerns. Despite my express request to be removed from their SMS marketing list, they continue to send promotional texts month after month. There are plenty more reputable multinational firms available.
Before engaging with similar brokerage firms, I strongly advise performing extensive research. Any organization that continues to send unsolicited SMS advertisements against your will is dishonest by nature. A credible institution would not behave in such a way. I feel they prioritize their personal profits over transferring deals from users to the market.
