Also as an additional followup comment, the legal structure surrounding banks probably impacts how digital robberies are targeted as well. A cyber-criminal organization who wants to rob some big player like Goldman Sachs, BlackRock, or Citibank of 9+ figures probably knows that they're going to have a devil of a time getting away with any big-time theft. The US government is actually going to go after anybody who tries to pull money out of big banks accounts to the point that they might even be willing to go to war in the right circumstance. If you're a cyber criminal, even if you could hack into some big bank systems and force a transfer, how would you get away with the cash in most cases? If they really target you with their full weight, you're probably completely screwed. In comparison, random Crypto Financial Agents are on many power-players "Naughty List". Depending on the exact circumstances of some crypto-robbery, the full weight of the US Government probably isn't going to be deployed against some cyber criminal organization who manages to take out a crypto firm's assets in the same way that they would if you targeted the existing banks. So maybe relatively more cyber attacks happen against crypto than other types of assets because it's known as a safer target. (I have no clue, this is just a reasonable hypothesis to me)
