startup ost? haha sorry for getting AMD but i get SO annoying with people constantly asking for startup ccosts and ROI like "HOW MUCH MONEY cAN I MAKE OMG MONEY MONEY MONE"

just like......understand.......that if u wanna do it "Right" you should have a fucin ddata center

so do u have the money to build ad run a data center? no? but u COULD if u slowly worked ur way up and used the bitcoins u mined to buy more mners!

But there is a real useful answer to ur question...the answre is aroun $3000 which s what u need for the best Antminer out there which gives u the most TeraHash for the lowest price.. for example the AntMiner s9 is gonna get you 13.5 TH but Antminer S9 is the newest one and $3,699 onEbay right now.....gives u anidea of the price.....and $300 to $700 for a 2600 Watt Power Supply for it

BUT u can start with a $400 Avalon6 and get 3.5 TH so yeah u could 10 of them for $4000 and get 35 TH so actually u might be better off fnding the AntMiner s9 for cheaper ive seen some for $1500 on amazon bt thats rare!

And u need a cheap rasberry pi to to ine on these ASIC machins but ya this is wwat u eeed to do it right....

and dont ask me for the ROI its gonna be a cople months probly 90 days ok? probly alot sooner ....mine bitcoin on it....mine etthereum on GPU vviideo cards so u need a nice gaming PC with nice videocard for like $800 and it will make u about $1 a day so will take u like a year to pay off IF ethereum doesnt go up in price BUT IT WILL go upp!

anyway just relax and know that if u buy soe miners u WILl make the money back....ddont worry about the return on investment so if u cant afford to go without tthe money back for at least half a year dont do it...but u NEED to do it and hoenstly why WOULDNt u be able to not afford it? this is how u ccan make urself a millionaire.....if u cre about money u would start mining immediately...

get a solar panel to power the avalon6 3.5 TH miner to start out! and that will colve the potential problem of electricitt being too expensive

just sart mining u wwont regret it

people heere need to stop worrying aboutthe eletrciity cost and the ROI time to g"get their money back" just relax and save the crypto OH it wont wor if u just sell all the coins u mine

u cant just mine the coins and immediatly selll them for bitcointo "pay off" the puracchse...nah u need to just accept the purchase of the mineer as a loss....and just save up ALL the coins u make and you will be SO hapy in a year hen the coin are worth like 100 to 1000 times more!!! look at the peopel HERE who talk about they had minerggate froom lat yar, forgot about it, and then just found out they had $500 !!! whenthey only ined themselves like $5! so u see how amazing this canbe?!!....And whenu buy agaming PC to mine, gaming PC is useful anyway u can use it for gaming too! But u wont wanna ull be makinso much off the ethereum GPU mining rig that u wllwat to fill yoru room with computers!!!!!!
