Helium mining in Pakistan

Dear brothers,I have watched your vedios about helium mining and I have few questions if you can respond I will be very thankful …

  1. What if I purchase 5 devices and deploy them 300 meters apart, would it be profitable?

  2. Is it legal in Pakistan ?

  3. I can not find it on any stores mentioned so where should I buy the IN865 device ?

  4. out of 5 devices which are necessary to create a block, every device will make almost 14$ ?

Please reply brother
