With the introduction of ASIC miners and the skyrocketing of network difficulty of bitcoin and most popular altcoins, it is currently very hard to be able to mine cryptocurrency using your laptop or PC.
However, you can now mine a wide variety of cryptocurrencies with your laptop or PC, via Minergate
Minergate is a mining pool, and a mining software provider, for a large number of cryptocurrencies. You can use its mining software to mine cryptocurrencies and make money online. I have an i5, 8 GB RAM, HP laptop with a 2 GB Nividia Geoforce VGS card and I use it to mine altcoins via Minergate and I manage to make around 8-10 cents per day.
Here are the currencies that you can mine using Minergate:
Ethereum, Ethereum classic, Bitcoin, Zcash, Litecoin, Monero, Bytecoin, DigitalNote, Fantomcoin, QuazarCoin, AEON, MonetaVerde, Infinium-8 and Dashcoin.
Minergate comes with a benchmarking option, that can help you audit your computer's mining power and estimate the amount of money you can make via mining cryptocurrencies.
If you want to experiment mining cryptocurrencies, or you want to make some money mining crypto with your laptop or PC, then Minergate will be a valuable piece of software for you.
