I know that it is very difficult to mine at the moment without special equipment, but I think in a way, even if it is a hobby, to try to mine either by developing a program in Java or with Excel.

I have basic equipment, currently I work with Minergate.

I want to make my own mining system, as I would do the following:

1. Connect to the cryptocurrency network.
2. Read the hash
3. Interpret the hash
4. Enter the new hash

And which currency would be feasible to undermine.

Thank you
