After reading the story I wonder how many google programmers actually steal crypto to make their fortunes? Likely some as there is no real way to track them. Not yet anyways.

So I wonder now how decentralized crypto really is? When more often than not the passwords we transfer through the internet to acces the blockchain of each coin investors hold has the potential of being stolen just on the basis someone like google or internet provider will also have access to the codes. This does not feel like everyone who participates have far share of their own crypto. Instead By using the communication mediums to verify our coin ownership can easily be stolen by the very few. Seems more like the same old where a few get rich while the rest gets nothing.
