Mining - Crunching Numbers

Ive started to look into mining. I have about 20k to invest in servers / equipment to mine. Ive heard ASIC miners are good investment.

I was wondering whether someone here could give an indication of the numbers we are talking about dependin on which equipment I would buy, what the average monthly earnings would be, and how long it would take for me to break even.

I am not fussy about which currency to mine, BTC, Ethereum or LiteCoin, but if I am correct each cryptocoin has different rigs that maximise the efficiency of hashin the individual scripts.



Thanks Guys
