Monero's hash rate is probably >1/1000 of Bitcoin when adjusted to equivalent energy. It is quite secure against 1000x attacks, especially considering they are not entirely effective as they were against some gen 1 alts. Algorithmically it is reasonably secure against 100x difficulty spike attacks (as are most other current alts such as Dash), though somewhat better than those that don't have a variable blocksize (again such as Dash) to absorb a transaction backlog.
That isn't saying much when BitCON is only using 1/1000th of the world's electricity.
So Monero uses 1 millionth of the world's electricity. Whoopdedo.
Edit: and downthread even ArticMine admits Monero is likely to lose 1/10th of its hashrate as block rewards decline to the tail emission, so that will be 1/10th of a millionth. And remember you and I were originally the only (vocal) guys who wanted a tail emission and rest of the Monero community didn't and Monero didn't have a tail emission before they realized we were correct.
