So the price is going down but the difficulty is going up. This has no sense. I have some scenarios but I'm not sure, can someone give a better explanation?
1. Difficulty grows because of ASICs
2. GPU miner move from mining Zcash & others (because the mining is not profitable anymore, so #1 again)
3. Something else above my knowledge.
I think there is no connection between the price and the difficulty it takes to do the mining for Ethereum. I assume you are here talking of mining, right? Anyway, I am not a good in many technical aspects on cryptocurrency much more with the mining technicalities but as far as I know those two are really not connected. These days Ethereum or rather the Eth is taking a strong beating by market forces leading many to assume that we are in the winter season where prices are not just freezing but going down. We just have to remain positive as there can be a big bull run after this...or so I hope.
