How many GHS would I need to buy to actually be in profit?
You can't be in profit.
Even if you use their calculator you can see that's impossible
It's impossible to make in profit until one GHS = 0.01 BTC
Really, let's use their calculator: https://cex.io/calc
I buy 100 GHS for 4.49 BTC
After one year I make the staggering sum of... 2.83 BTC... not to mention that after ten months the maintenance fee will be higher than the generated bitcoins, meaning you start to lose money
Thank you. I guess I'll scrap that idea. I wanted to order a monarch card from BFL but by the time they deliver it, the 600ghs will probably not be enough given the rise in difficulty.
