550 Bitcoin computers? I assume are the dedicated type, not general ones like the one I use to type my comment. If so, those go obsolete in like half a year. The heist, with its mined bitcoins, its maximum of several millions (USD) at best, even at 20k USD/bitcoin. Become a politician, you'll get these money and much more in those 4 years of a single mandate, all legal because they are called donations.
