The general population still has a misconception that you can mine Bitcoin on your computer.
Not only on a personal computer, but also on a smartphone - which leads us to millions of people downloading various applications and
mining some coins with them, hoping that they will earn something on that way. The only ones who make money are those who collect their data and show them ads within those same apps.
Ignorance is a great friend of all those who want to make money through fake projects, and the story about Game Boy should be understood only as one interesting thing, and certainly not the last in a series of
"I learn my x device to mine BTC".
We would might see another device that would be modded for this kind of purpose but talking about relevance then i cant say it is totally useless but thats only for some educational purposes or some sort
of hobby or interest on making things possible specially on that Gameboy mod above where it can or really shows of some hashes that it can actually mine compared into those
mobile phone mining apps which are totally piece of crap or just totally been deceiving out those newbie minds out there.
Talking as a whole about its usage then its really works but doesnt mean that it would be worth have any sense on using it.For the sake of hobby and past time then
its not a bad work after all.
