Mining of cryptocurrencies with mobile phones? WTF !!! It's not profitable!!!
Cryptocurrencies Electroneum and Stellite are two examples of mining with a mobile phone. But is it profitable?
In my opinion it is not, I have never tried it, nor have I used old or old phones.
Using any type of mobile, used or new requires a lot of attention, electricity (little electricity) and damages the environment by inflating old batteries. My common sense tells me it's not worth it.
Currently Electroneum promises 3 dollars a month on average with mined by mobile, and Stellite is a cheap currency, it is more profitable to buy it in 11 satoshis than to mine it for mobile.
What is your opinion?

@therealwolf 's created platform smartsteem scammed my post this morning (mothersday) that was supposed to be for an Abused Childrens Charity. Dude literally stole from abused children that don't have mothers ... on mothersday.

I think it's good to get three dollars a month. It's also not about making the people there by phone in industrial countries. But in Africa, with $ 3, you can survive half a month
