Cheap? Free?
- Italy cost per kilowatt is one of the highest in Europe; if you happen to steal from private use (households, factories...) you will be busted at their first electricity bill;
- since 16 years, Italian energy grid features smart electricity meters everywhere; you'll get immediately busted if you plan to steal electricity from public lines (today two guys in Ischia were busted for this reason, did you hear? and those 19 arrested at the Infernetto, Rome, a month ago, do you remember?);
- solar insulation for central Italy is about 1250 hours/year, if the mining rig requires 15 kilowatts continuous, you'll need a huge solar farm, at least 120,000 Wp panels
- Rome (and surroundings) is infested with gypsies, burglars and gangsters (some of them are Italian), plus drug addicts and weirdos who love trespassing
TL;DR: local proverb says: "your head's only function is to keep the two ears apart".
