He said is from Argentina and that means 50% import tax which means a rx 570 which can be bought in online stores for around $250 in the USA, in Argentina you trolls need to add 50% to that price and then you trolls can give him advice if is worth or not.
"Argentina operates a Simplified Tax Regime on postal imports wherepersonal imports valued between $25 and $999 are subject to a flat tax rate of 50%."

So lets by parts, a celeron cpu $40, 6 rx 570 = $1250, psu = $200, memory $100, ssd $70, motherboard $120, risers $50, now the total 40 +1250 + 200 + 100 + 70 + 120 = 1830 dollars, now put 50% more from import tax = $2287, now you have the total value you are going to spend more or less, each rx 570 will consume 120 watts + other things, so 840 watts, i already calculated to you your return of investment, with electricity at $0.04 will take you 2 years or 702 days to get your money back, is it worth your time and money, no, cause if you buy cryptcoins right now and wait 2 years then your cryptocoins will be worth 5 to 50 times or 500% to 5000% hassle free more whereas mining might give you only your money back which is 100% and will give you lot of headache plus if one gpu dies then your roi is 18% delayed, from 2 years to 2 years and half cause forget warranty if you live in argentina cause they dont give it. So all in all, dont waste your precious time with mining.

Does it give your money back in 100 days or less? no, so it is not profitable to you and for that matter to nobody, earning peanuts and being happy about it, is the same as people working very hard for a minimum wage and the rich laughing at you. Do not be an idiot, be smart.
