Is Coinbase a scam?

Could you please elaborate on the legitimacy of Coinbase? I've heard some rumors suggesting it might be a scam, but I'm not sure if there's any solid evidence to support that claim. What are your thoughts on this? Do you consider Coinbase a trustworthy platform for cryptocurrency transactions? Or are there any red flags that I should be aware of before using their services? I'm quite interested in investing in crypto but I want to make sure I'm dealing with a reliable and secure platform. Thank you for your insights.
