I think it have to work because someone have make millions with spotify like that
A mobile phone cost here like 30 Dollar with Android
10 x 30 =300 Dollar
For charging its nothing muxh to pay
That means i can make with 10 Phones 24/7 something to earn btv but i dont find the right way
Sooner or later the Spotify will ban that account because using multi-accounts however he commits a crime that can make others lose.
