Some mining farms facing issues with their profitability at current BTC prices as it trades on break-even cost
of mining. Miner`s earning has declined significantly as the mining difficulty has increased and the BTC price
decreased. This is not a problem worldwide as it depends on the price of electricity and there are still countries
where it is cheaper and the mining is still profitable.
I think that this is not time to sell what they mine. Propably they sold on high and they have for current electricity bills. But it will interesting what will happend when current market cap will not rise and stay on same level during next years the will wait or maybe sell their gear xD.
