I had been sitting on the bitman site the entire weekend. 2 items in the cart ready to go. But Thor's this damn post was nagging me the entire time. Did a bit more research and every Reddit post about mining says the same thing.
In the end I decided not to buy and instead to the additional 10K in Ice3x and bought more BTC. I'm now up 3k ZAR since Friday. Also due to shapeshifting half of everything into Eth.
Some good advice for anyone else wanting to get into mining. If you can buy an ASIC when it's cutting edge and hasn't been mining for 3 months for Bitmain before you buy it, you're good to go, all other cases, buy and hold.
You were right Thor, thanks for the advice.
