I'm afraid that with the current market in downtrend, altcoin mining is not really profitable. Even with cheap electricity, if you use GPU, you can earn very small amounts. The only exception is maybe if you can employ ASICs and mine the alts minable by ASICs. Not all of them are profitable, but with cheap electricity you can find a couple of coins that can bring you some profit. Check your options at

I will check the website and see if it is possible for me to find any coins to mine with my office electracity. Thank you also for making some recommendations.
Its really not worth the hassle these days to mine. Even if you got power at 10cents a kilowatt, which is considered average you will end up almost breaking even. And you need to consider the cost of the GPUs, PSUs, mobo, and any failures along the way.
Most these days put their rigs on hold and are basically waiting for the $1/day/gpu before they turn on their rigs. Not worth mining to make $0.05/day/gpu which is the current profitability at the moment.
If you believe in crypto, just save yourself the headache and just buy the coins directly.
