of course if I understand that ... what I mean is that the profits are huge and even if there is a drop of say 50%, the profits are still huge !
I don't know much about mining, I'm a "beginner" as you say but it seems impossible to me that in less than 2 years the profits drop by 50% on an ASIC...
after if I'm wrong tell me ^^
We do not know how long the bull market will spill.
We do not know how long Ethereum mining will be relevant.
We do not know how many ASICs will be produced and sold.
After the end of Ethereum mining, this ASIC will be useless.
There are a lot of investment risks.
