My father is working at electricity and we have electricity at 10% of its price.
So, actually, it is 0.15€/kWH and so it is 0.015€ for us.
Is it profitable ? Which miners should I buy ? Which coins ?
Thanks,
Xavier
First check www.coinwarz.com
Check the coin you want to mine.
Check the various mining equipment you want to buy (hashrate and power consumption in watts)
Enter them in coinwarz and you will understand if it worths mining.
Also have in mind that diff is rising.
When I first bought a miner years ago, it could mine around 4BTC per month by the time I ordered it from BFL. Delivery took 6 months. By that time it could barely make 0.05btc in a month.
