Man...so much negative energy on this post! OP...how soon will you be able to get your rig up and running? If you are fine with not getting immediate returns, then I will highly recommend building your rig and start mining and hold on to mined coins.

Let me share my experience from 2014, I mined Monero (XMR) for about 5 months in summer (using 1x R9 290X+ 2x R9 280X) and finally quit around Thanksgiving because the XMR price was shit. However, I held on to those coins and finally sold them last September, when we had a big XMR spike and recovered the money I paid for my gaming PC (~$2k)! Had I kept on mining during 2015 - early 2017, I would have made much more, as many of my friends did mining ETH. But hindsight is 20-20. Anyways, what I have learned from that experience is that always think about the long game and price of cryptocurrency (if it is any good) will rise eventually and you need to be patient.

Good luck!
