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?
Why are you worried if the price will go down under $6K? Remember that last year bitcoin was at $1k and miners were doing good. It's just a psychological effect and everything will follow. Believe in this technology as this will bounce back soon.
