Buy a Special Router and Earn Passive Income with Helium (HNT)

Once you’ve paid the up-front cost of a router and set it up somewhere in your home, a new-ish project called ‘Helium’ really could offer some ‘passive income’.

It’s unclear just how long it could take to recoup the cost of that router, since it will be mining the cryptocurrency HNT, as long as your hotspot remains online.
