Let’s see:
576+/- blocks are mined in a 24 hour period.
We’ve been around the 5.5 million kh/s network mark.
You’d need to find 2.5 blocks a day to make 500 FTC.
Solo or pool mining, you’re looking at 20,000 kh/s +/-
You’d need 23 R290X cards running optimal at 880 kh/s - based on a quick hardware comparison google search.
If you are lucky enough to find them for purchase, it would cost you $14,500 USD.
This doesn’t include the PSU’s, Motherboards, Risers, Drive or Pi + Frames and Electricity.
I’m guessing hardware alone would be in the $18,000 range.
At .27 USD cents per FTC - it would take you [considering difficulty stays the same, as well as the price; you have no hardware issues, electricity is free etc etc] 133 days to break even.
OR
You can buy the FTC outright [this is assuming you are going to hold until price goes up] via BTC or direct from someone using escrow, or Bittylicious.
There is no real easy way of mining FTC at such a volume - and depending on your position, it would be more cost efficient to just buy it outright.
