800 is an absurd fantasy. There are like 20 BTC atms in las vegas. I think one of them chages spot plus 7.5 percent(obv on the other side of town from me), and the other 19 are all 10% or above. This one sounds like its at around 22%, which is at the high-end of typical. I actually don't buy my own any more, but i always used to feel like a complete tool when i would have an after hours or sunday shortfall and have to resort to the ATM.
Its not impossible that this guy actually owns it, but depending on where you live, its either very very unlikely, or very very very unlikely. Hes probably just leasing it from the real operator. You actually need a ton of licensing to operate BTC atms in most jurisdictions and its not worth it to jump through the legal hoops and pay the fees involved just to stick one in your little mom 'n' pop store.
yeah, unfortunately we can't get away with that in vegas theres super tough fincen here.
