Depends on the bank, if it was my bank I’d probably be able to afford a nice steak dinner and that’s about it.
A real bank? I’d feel really bad but playing along... I’d build a really killer home movie theater. Buy my neighbors house (they suck but have lots of good friends on the road) and turn my house into a 1 story taking up both lots. Hire someone to do the pool so I don’t have to constantly deal with it. Buy a few hundred thousand steem while it is low and put the rest into bitcoin and ride it up. Oh and I’d hire a full time chef.
