For mining bitcoin cost of electricity is 0.10$ per kwh is best
rizwanali - You are exactly right.
But now a days many even don't like mining bitcoin who can have the best calculations, my buddy do recommended me.
have a look on coinware to understand what is happening, you can analyse the profits, usage etc.
Free electricity is better
how ever solar/ wind energy is even a better way to opt.
You know in canada it is 0.35 kw/h, it is higher than most parts of europe, and the regular price is 0.06$ in QC - Canada.
Look on the Metrics at central washing ton it is 0.027 kw/h.
it is like we need to spend $10 to earn $4 sometimes.
You can use cryptocompare site to know the profit can make using the miner you gonna use for mining process. We cannot understand that mining cost in each country instead they check the directly with the mining calculator available in online.
If you can go with buying the ASIC miners you can make more income in mining. that is the case.
