What are the benefits of mining cryptocurrency?

I am new to Mining Crypto currency.. I have limited resources to Mine can anyone suggest me, Which is the best Crypto mining where I can earn more profit. Earlier we need big computer to mine now I heard that from Home PC we can do? Since I have limited resources please suggest me better option. Earlier I am doing mining with My mobile phone but after wasting two years I don't received output what I was told. I mine Pi coin on Mobile Phone and Bondex I mine they both taking years I get bored with them without earning anything! Just waste of precious time and effort. So this time I think of find some genuine mining where I can earn decent crypto currency per month with some investment. Waiting for your Advice ????
