Hello @kouba01,
Thank you for submitting homework task 5 ! It was a really good read with lot of information. You have discussed all the three topics well with clear facts.

The need to trust third parties. In this case, the provider of computing power.

This is the major disadvantage I see in this concept. There are lot of scams in the industry. So should always find the reliable platforms to invest ! Good job [9]
Thank you
