I heard most of the miners are shutting down their gigs, Is it true? So, Is this the end of Bitcoin? 
There was an article about miners in China shutting down their rigs and this has nothing to do with cost of electricity or difficulty, but this is more on the equipment itself reaching the lifespan where it needs to be shut down or replaced or else maintenance of such equipment will be more expensive.Chinese miners are always going to be the last ones shutting anything down. even if their equipment is outdated they simply upgrade it since they have access to fast shipment of ASICs from Bitmain which is in the same country and easy to access.
besides ASICs don't expire all at the same time! there was new versions released which made it less profitable to run the old ones so some started shutting down or upgrading. that shouldn't cause much of a hashrate drop in my opinion.
Well in the real world, and not the fake believe HODL world, but according to whattomine.com, right now an antminer S-9 causes you to lose $1/day
Thus in the real world who in the hell is keeping their miners running? ALso in the real world, it take +2 years to find a bitcoin, but the reality unless your on a chinese mining pool, you ain't going to get that bitcoin, cuz they got 90% of the miner's, and they decide who 'wins' the each round.
S-9's will become dirt cheap, I get offers every month from BITMAIN for $100 USD ( I'm assuming they're used or rehabs ), but the deal is they got a huge stock that ain't selling;
Only in places where the electricity is less than 0.05 per khw can you make profit at todays difficulty, but the only place that is that cheap is venezuela, ... which is in a civil war, and mining is illegal, so if you go mine there and get caught you win a spot where you will starve & die in the mud,
The only rational thing to do with S-9's is to use them as space-heaters, and accept the fact that any btc you win is a lotto-win, I think millions of chinese will be having s-9's in their homes, but that said you must enjoy 110db sound of jet-engine in your house, so sound-mufflers will be the next 'big thing' if you want to get rich
