Please, just stop with this f.....g nonsense!!! Did you even realise that outside are parts of the world where you earn just 50dolars per months for a very hard work 16h per day 7days per week?
And You just getting a very good ammount of money almost for free!!!
Permonik:
You can't compare the income in a part of the world where $50 a month is a lot.
There are few people that would spend (or have) 3 years of income ($1750/$50 a month= 35 months) to buy an Asic.
If you make $50 a month you would be nuts to risk 3 years of income on an ASIC.
Dude - simple math...
ASIC A3 is making $30/day.
$30*30 = $900
Cost of 1 A3 - ~$1,000
Breakeven = 1 month
Say difficulty goes up and you only make $15/day...
$15*30 = $450
Cost of 1 A3 - ~$1,000
Breakeven = 2 months
I don't know what universe you live in but a 2 month B/E is hella good in the business world.
