for now my income from bitcoin is still small. dream I want to save to build a machine for bitcoin mining that can produce 5 bitcoin in 1 month. so I just wait for bitcoin every month. looks like it's so much fun.
It will not be fun to mine because it is boring. You will just leave your equipment and maintain it.
The fun there is when you are receiving the bitcoin and making use out of it. Imagine not doing anything anymore and money is coming to you. Just dont be shocked with the electricity bill.

i think for now the mining in cryptocurrency is still quite profitable, it proves my friends have many rigs and other mining tools in their homes, yeah the problem may be on the maintenance as well as the electricity, but if you really want to have a dream to earn big income from mining, you also have to make an idea how to minning with electricity from the energy by make yourself like hydroelectricity or etc, may be more efficient, and profitable,,
