Some projects are actually offering mobile mining just to attract more investors. As for me, there haven't been any altcoins mined using mobile phones with good value. It's just a waste of time and will only consume your battery. I just wish that there would be great coins who would allow profitable mobile mining in the future.
Until now i dont think to see project that has a real good coin value that used mining trough mobile phone which i think a waste of time and by dead we kill our phone for a dime useless token. They should create something that more effective way to offer mining from mobile phone without killing our phone.
