It is true that all is possible and we have to be ready whatever happens. But, in my opinion, it is highly unlikely to go down to $2k price per BTC. $6k is the approximate mining cost and miners needed to pay for the expenses. They will not sell anything below $6k, which will likely be the cause for scarcity on BTC, therefore, institutional buyers will most likely buy at that price level and we may have another bull run.
Not true the mining cost is like $3k in China which is the main producer of bitcoin and there's nothing to suggest miners won't sell for a loss if nobody is buying. Better to take a loss than to make no money. So it could EASILY go below 6k and I think it will go to at least $5k. I wouldn't buy it at that though still overpriced.
