Any were there is money scam is always not very far away a  lot of people have been scammed especially in the crypto ecosystem, especially about platforms that will tell you to invest a certain amount of money to get a greater return is a scam and called ponxy scheme, And that particular scam, which many people fall for, uses either pretexts that they are undergoing maintenance before you realize the site is inaccessible, or it uses other deceptive tactics. Before investing on any platform, perform thorough research before depositing if you're still unsure about if you'll be able to get your money back if it's a fraud. I wish people will stop reading about money doublers.
