well sollar energy as wind would be the way to be able to roi but how many time you think withoyt pay eletricity would take 1 year? more less with the current price of 230 dollars.... would be better to sell and buy it ?
Don't forget that with solar and wind (or any other electricity source you buy and generate your own) you will have to ROI on the investment for that device too, on top of the miner. Essentially, it only extends your ROI and makes your income higher after the break-even point, where the difficulty probably would have already risen.
sollar as wind energy would be only to mine lol you can use it at home there is a lot things to spend those energy from them lol...soo this investment is to ROI around 5 to 10 years of bills
I didn't fully get what you were trying to say. However, there is a big difference between 5 and 10 years of ROI.
if you think in future you can say on the next 20 at 40 next years that you expect to be alive ,what i meaned is that is currently several people that invested on wind and solar energy soo mine bitcoins for any person that goes into these new ways of energy will be roi on the next years that is around those time as the country you present at brazil is around 10 years....the normal energy costs....
What i meaned is you can take a shower turn on light ,turn on pc ,turn on tv, and mine bitcoins with the new energy soo is what i meaned
