@chesatochi Miners are going through ups and downs. :P Mining is becoming difficult day by day as the mining difficulty is increasing. To be little bit technical, miners are struggling to find nonce value. :D

If someone wants to start mining, he/she should go for altcoin mining rather than bitcoin. Most of the altcoins are still serving profitable mining and network difficulty is also under the hood. I am using my smart phone to mine electroneum. Though the mining power and output is less, future value of the same number of coins will be more.

I am finding some more ways to mine other altcoins from smart phone or laptop.
