Would you be interested in a cryptocurrency with its own blockchain that can easily be mined on both android and iOS phones?
if you mine BTC or other alt coins, you may see that a very high power needed for effective mining, so I think mining with mobile will not had good result and gain
1- mining need high power energy ssystems
2- mining need graphic or cpu with high hash
i think if mobile manufactures design this mobiles phones the lyfe cycle of these devices will be very short for above reasons
