How did FTX get so much money?

Could you explain to me how FTX managed to attract so much capital? It seems like they've been able to raise billions of dollars in a relatively short period of time. What was the key to their success? Was it their innovative technology, their experienced team, or perhaps their strategic partnerships? And how did they ensure that their investors' money was used effectively and securely? I'm really interested in understanding what made FTX such a popular choice among investors.
