Ive got one of my Antminers posted on Leaserig and a person keeps renting it but I have a few questions..

This person has his pool setup to a IP addrress and he is getting very slow hash rates..  50-70ghs

He keeps re renting for 24 hours.

Here are the Questions:

1) How can he be making a profit?

2) Any idea one whats actually going on here?

3) Any way to determine what coin he is mining?


Normally I could care less what a person is mining but im amazed he isnt bitching about the slow hashrates so he seems to be happy with the slower rate.. so naturally it set off redflags when he keeps renewing.  I guess i want to make sure nothing illegal could be going on here like using the machine to do something malicious.
