I'm sorry, but your question seems to contain a fundamental misunderstanding. FTX, as a cryptocurrency exchange platform, did not "steal" any money. Its collapse was due to a combination of factors, including poor management decisions, regulatory issues, and market volatility.
However, if you're asking about the financial losses incurred by users or investors due to the collapse of FTX, that's a different matter. The exact amount of money lost is difficult to determine, as it depends on various factors such as the size of individual investments, the timing of withdrawals or trades, and the value of assets at the time of the collapse.
It's important to note that cryptocurrency is a volatile and unregulated market, and investing in it involves significant risks. Before investing, it's crucial to conduct thorough research and understand the associated risks. Additionally, it's always advisable to diversify your investments and not put all your eggs in one basket.
