Can BTC technically survive under 6k?
This is close to a bottom where mining stops to be profitable, meaning that supply of BTC from miners would drop. How much supply comes from miners anyways? Is that meaningful in terms of price movement?
What if miners are not profitable? Does that make them stop and thus make BTC transactions less secure? Do they continue mining in hopes of future price raise?
What would be the psychological impact on traders if BTC goes under 6k? That is a huge resistance point and if it brakes how far can price drop? Last time it was more like a test to 5800 which recovered immediately.

How much of supply comes from miners? What You mean? If You ask how many coins they supply, then 1 coin in every 10 minutes. If You ask, how much of calculations they make, then its 100%. They are the backbone of BTCs claimed product.
I particularly like You 3rd and 4th question. No, it wont make transactions less secure, it will cease the transactions, because calculating the blockchains IS the transactions.
Yes they do continue mining for a while, but not for long. People who believe in god are very... persistent. BTC is their god.
