Topic: Is the efficiency of mining BTC gone? - page 2. (Read 439 times)
It's only for business based miners with a warehouse style setup, or for people with free electricity and don't want to bother with other altcoins. There are are serious miners closing shop due to the price drop but that will change next year as the market recovers
I would like to hear your views and experience.
I guess by efficiency, you mean the profitability of mining bitcoin. I will simply tell you years. Bitcoin mining is no longer profitable. It is best to forget about mining, and invest a little amount to buy some bitcoin instead of trying to mine. 
Efficiency has increased near infinitely since bitcoin was first minted, alongside that difficulty has also increased massively. At the moment it would seem for a lot of people bitcoin price is too low to mine profitably and that's why we've seen recent drops in difficulty.
I would like to hear your views and experience.
