I wonder if it'd be a crime to exploit a cryptocurrency and route massive amounts of money to a null address. Technically there was a lot of ““money”” lost, but you made no profit and since the blockchain is public and distributed you weren't “illegally accessing a private computer without authorization” (well, depending on the exploit). Maybe a civil suit for damages but I don't know how much a judge would be willing to indulge a plaintiff whining about fantasy money with dubious actual value.
