How did FTX raise money?

Could you explain to me how FTX successfully raised funds? I'm particularly interested in knowing the strategies and techniques they employed to attract investors. Was it primarily through initial coin offerings, venture capital investments, or some other innovative method? Additionally, how did they ensure the trust and confidence of investors, especially in such a volatile and uncertain market? Finally, do you think there are any lessons that other cryptocurrency startups can learn from FTX's approach to raising capital?
