lol no I highly doubt it was a Bitcoin mine, it wouldn't explode like that but burn slowly. This explosion had to have had some accelerant or something, some chemicals or maybe even a bomb or something, there was a shockwave from it.
I don't see it being a bitcoin mine with the explosion I agree. Only possible way it was a bitcoin data center is if it was shared warehouse and other part had something explosive in it.
I don't see anyone being that stupid personally on mixing explosive and lots of electricity. So don't think btc. But guess in next few day's we will know a lot more.
