So, what is the lifespan of USB Block Eruptors? When are they expected to fail, die, overheat or otherwise stop working?
What if you are going long on BTC and are hoping to mine as much as possible and sit on them for the value to build (hopefully all the while still slowly upgrading and adding more hardware)
In theory if you keep them cool they should last many years.
But I don't think anyone will know for sure until enough time goes by that people start to see them fail.
When bitcoins were at $15 a lot of people were saying GPU mining was dead because the cost of electricity made it unprofitable.
Then the value jumped and it was profitable again for a while...
Perhaps the same thing will happen again.
Sure, its easier to just buy coins and sit on them but its a lot less fun than tinkering with hardware.
