How did FTX spend 8 billion dollars?

Could you please elaborate on how FTX managed to spend an astonishing eight billion dollars? I'm genuinely curious about the strategies and decisions that led to such a significant financial outflow. Was it invested in various crypto projects, or was it used to expand the company's operations and infrastructure? Or perhaps it went towards marketing and advertising efforts to attract more users? Could you please provide a breakdown of these expenses and explain the rationale behind each allocation? Thank you for your time and attention.
