I heard most of the miners are shutting down their gigs, Is it true? So, Is this the end of Bitcoin?

GIG or RIG?
My first thought was like most posts on this forum it was a HODL'r ( retarded person ), and he was quitting his day job (gig)
I think most HODL'rs don't mine, they buy, as they have been told, besides long ago the investment for an s-9 was so high, they were told its better to buy, than mine, ...
So we don't know here if this person is talking about quitting a job, or shutting down their rig
It's not the end of bitcoin, because when the rigs ( take the s-9 as a base ), go for $10, people in china will buy them as space-heaters, and the accept the cost of electricity, and buy them for the added good of winning the lotto.
My fear is that new software will be deployed for mining only, and nobody will be running full servers to process transactions, thus BTC will be in deep shit, cuz the tx rate will go from bad to worse.
Remember an ASIC miner doesn't need a hard-disk ( full block chain ) it just needs to call home and get work and send back a hash that is led by 'N zeros'.
Now that running a full-node doesn't make you money because mining is dead, ...what's the point.
Lastly, difficulty will not drop cuz all these miners in china will be running as space heaters, thus price goes down, but difficulty goes to infinity.
