dude, i can't belive you have so much activity and still know nothing.it's either you play dumb or ?are you that dumb ?it's not just 14 BTC, you have to add import tax, psu costs,maintanance, cables, everything else ! with all this money you can buy 23 btc from start !
I think you're the one playing dumb.
Why would you automatically assume everyone needs to pay ridiculous import tax even though the majority of people mining don't?
Also not everyone is forced to buy the most expensive ATX psus possible.
