Hello. I would like to ask, If I buy antminer, Should I mine after 2 or 3 years or it will be unacceptable?
But we don't know what will be the BTC value after 2 or 3 years, so... Part of us will say that it's better to buy some BTCs right now, another part will say that you better start mining ASAP... 
So you see how multifaceted this subject... A matter of perpetual debate...
