Hello, Im recently studying cryptocurrency stuff and looking for what to miner in windows 7 with NVIDIA GeForce GTX 750 Ti and how to do it 
Currently CpuMiner is easier and is running here so I thought to increase the hashs
The best advice for you is to mine a equihash crypto. Currently CpuMiner is easier and is running here so I thought to increase the hashs You have to find an alt with equihash algo, where nVidia GPUs are the best and a little crypto, with a not too big difficulty because your GTX750Ti is a low GPU.
There is a lot of cryptos with equihash alg.
