We are all on the move regardless if we are travelling to work or aboard so it is not surprising that there is a crypto mining app for android and iPhone devices but is there a real mining app?
It is true to say that the miners profit margins are not what they were in the past. In fact many home based Bitcoin miners have stopped mining for that reason. It is quite understandable because the home based miner may have invested a lot of money but found the expense was not worth the income from the miner process. The expense would have included several mining rigs costing between 2000-40000$. Then there would the the power needed to run the rigs which in todays prices and lot of money.
There have been some cheaper options such as using your web browser which for a while was a great way to make some extra money. For someone new to mining it is still an option if you are willing to use the affiliate program that allows you to build your own mining pool.
