The ongoing FTX saga has injected more uncertainty into an already shaken market. If it was not clear already, even the biggest centralized exchanges can fail. The problem is multi-faceted. On the one hand, just like in traditional finance, centralized institutions are only as good as the people who run them. When investors use services like FTX, they are putting their trust in the people that run the service. Unfortunately, history is rife with examples of powerful people taking advantage of that trust.
On the other hand, cryptocurrency is still very new. The vast majority of crypto users are not well-versed in all of the technical underpinnings of how things work. For most, digital assets are simply an alternative means of investing and therefore the most convenient solutions are often the most popular ones.
