Cheap BitCoin mining setup?

Do you guys have any cheap (well its not that cheap but the cheapest) mining rig?
and which sites/programs should i use for it

i use minergate for mining, and not need high performance graphic cards. just need an server or cpus/gpus

My "mining rig" is my gaming computer with a GTX 960. It would earn around $1 a day if I ran it 0-24, I sometimes start the miner up to earn some cents while I know I'll be away but I won't turn off the computer just yet. Electricity costs less, so it is still worth it, even if it is just a few pennies each day, it adds up over time.

Whether youre building your own PC for the first time or youre an experienced veteran,

Buy 1 graphic card, 1050ti for ethereum or rx 560 for monero. And start mining. When you will have enough money, buy 1 more. So in few months you can build your own rig. This is the cheapest way!

Generally its a waste of time in my opinion it costs too much either way.

Define cheap? $20K? $30K? $100K. More specific info about the budget more easier to give you a suggestions

In my opinion mining btc is a waste of time maybe search around google on how to mine monero.

Yes, I have long wanted to do bitcoin mining but did not know how

A small Titan X, only 3 thousand euros ^^ ! No, 3 or 4gb are fine ^^ !
