What it total possible Soilcoin supply? Considering difficulty and block reward, price should be about 10k sat (for difficulty 1.000.000 M, now its 190.000M) to make it profitable to mine.
the difficulty went extremely up in the past 48h - you can mine now less than 50% of what you could do 48h ago with the same hash-rate.
below 3k sat you can't even get coins for 1 BTC and from 3k sat the profitability for mining would be ok already - it might be just a question of time till the price will follow the difficulty - no serious miner would dump his coins now at low price just for very small profit.
