Beginner's questions

Hello,

I have some questions concerning M2 pro:

  • is the placement of the device really important ? (I know that it really is for hotspot like for the helium project, but I wonder if its the same with this device since it is more powerful, i understand that basement isn’t the ideal place but , once again, is it necessary to adapt an antenna to the device to device to increase it s range ?)

  • how does the “proximity” of other M2 pro device impact the mining yield ? (the minimum distance from the others device, is it important to have other M2 pro in the area, etc…)

  • I understand that it is possible to mine different crypto, but is it at the same time or one crypto at a time ?

If you have link to videos that explain the answers to theses questions please, send it to me.

Thank you for your time.
