Thanks!
I don't really care about profitability right now, but only about the traffic that is created. Do you thing I will get any accepted shares with this Antminer T9? If not, is there any other cheap miner I could use?
Yes any SHA265 miner will work. You could use a Antminer S9, S9i or T9. You should be able to buy these on Amazon, ebay or Bitmain's site (the one that manufactures these ASIC miners). Remember to buy a compatible PSU or you would not be able to run them.
I am however not sure if you would be able to capture any meaningful data unless you are only looking for how much data is transferred over x amount of time or how much bandwidth is being consumed.
May be if you provide details of what exact data you are trying to collect, people in this forum would be able to help.
