When he says the Blockchain stopped to work, it has to be taken at the second level of humor. It's a sarcasm. Of course, He knows the blockchain didn't stop to work. He is not so dumb to really believe such thing. You guys are really sensible
I beg your pardon.
The blockchain stopped working a few years ago when bitcoin hit 1000$ and since then he is unemployed and spending all his money on drugs and (!).
Now, to all the others who already started another altcash
BTC war, it is not about the hashrate.
The hashrate doesn't matter really. Even if all miners by some miracle would switch to altcash the blocks will still be mined until the last cpu miner stops.
The blocks will arrive a little late as difficulty adjusts but that's all.
And with bitcoin surging over 4000$ I doubt there aren't hundred of miners being plugged in each day.
