According to the FBI, BEC fraudsters took $1.8 billion in 2020 by stealing wire transfers from businesses into their own accounts https://www.ic3.gov/Media/PDF/AnnualReport/2020_IC3Report.pd...
I see the point you are attempting to make but the number is rather useless, in the past week hackers took 20% of what was stolen by BEC in a year. And skimming through the report you sent it seems like there is a program to recover said funds that have been lost and it has an 82% success-rate.
Either way two wrong's don't make a right, there will be losses in both systems but I would argue that storing your money with a unregulated crypto-firm would be more dangerous than with a modern-day bank.
I think the main gripe that many people have including myself with crypto is that it doesn't even have the proper consumer protections so that a decent/strong chance of recovery is possible.
This trend of massive amounts of crypto currency being stolen is not even a relatively recent one, see Gerald Cotten's (Quadriga) death in 2019 which resulted in $150 million in assets going missing with no chance of recovery.
This reply has been a little-bit scatter-brainish, so my apologies for that.
