roi is return of investments, basically the most important thing to calculate before investing in anything

Amazon will sell you one that you'll never be able to make any money from. But you can still mine.
 

better to buy one used, you will achieve roi faster, no need to go for the new toy in the mining scene

[rkandrades]

Try http:/aliexpress.com

I saw a lot of models being sold there. Good luck!

[Agaguk24]

I strongly recommend Bitmain; they have always ROI'd for me...

[LimitedDev]

on many sites I should order in large numbers but I only want 1 or 2 miners..BTCBTC

You may want to check on eBay. I have bought some if mine  there.

on ebay or local bitcoin community

ROI is so individual there is not one size fit's all.  Likely it depends on electricity prices in most cases.   But there could be much more to it.

What is your electricity price?

only thing I know about..... 8gh stock usb stick 25 bucks with 6 bucks shipping (2 for 56 bucks) works just pop'd mine up and up to 3 of them at 6 buck shipping price

now the only ROI is a smile but what the heck ..if you need to get a miner at least you won't get burnt....


these are NEW by the way




check out these links if you need a blinky light toy

this is a for fun project......as you can tell my hope is they eventually can get some modern chips and make something a bit bigger (again unlikely to ROI but toy wise they
can't be beat)
 
below is links and pictures on how mine is setup (also my other stuff) here is the bitcointalklink on setup etc

anyway ...will get me thru them 'cold nights' when the last of my home miners are doorstops (home mining is dead)

and I also got a bitseeds v2 bitcoin node device just so when that happens last year I can still feel I'm contributing something to the network

(withdrawal symptoms ...whatever helps the home miner withdrawal  ..trying to be proactive)

take a look at the miners from bitmain or hashnest (with hosting)
Bitmain is the most serious mining hardware manufacturer

[Lenore]

You should try cloud mining. Check my signature.

^^^  SHILL!

Cloud mining is DUMB and also NOT profitable for anyone except the person charging you fees. CEX.io WAS profitable until the end of last year when they started "black-outs" and charging maintenance fees greater than what the hash produced.

DO NOT BUY CLOUD HASH

it is a SCAM, IMOTHO

Cloud hashing I really don't understand.  Why don't the owners just use there own hashing power to mine.  Unless they sell the hashing power for lower then what is potentially mined it doesn't make sense.  Except for the fact of the instant BTC payment for buying the hashing power.

There is just really no money in it.

Update, today started a new campaign with btlend basically allow you to buy and share using the btlend pay after 90 days !!
In addition you are using the code btclend you have 12% discount!
To use it:
1: register on the site: https://www.miningsweden.se     ref -->  https://www.miningsweden.se?affiliates=118
2: create a wallet here: https://wallet.btclend.org           ref -->  https://wallet.btclend.org/Account/Referral/FKnmIkC
3: go to the shop and pick the product
4: insert  discount code btclend
5: you have 90 days to pay, logically interests 0.

No, you can not ask for the documents cheating !!

Ps: those who want to offer me a cup of coffee you use my ref !!

 
     

cloud mining now is not profitable, There have been plenty of scams and frauds in the Bitcoin community.

amazon.com provides BTC miners

NO NO and NO.  Don't buy on Amazon or Ebay, you will pay way too much.

Check here on the market section for a used btc miner. Like Hazir said, you need to understand that ROI is currently really hard to get. Except if you have a really good electricity price.

Check for a S5, a SP20 or a Avalon4.1 they are the best miners right now.

Have you bought from anyone on here?  Can you recommend anyone I can trust?   How would I know to trust someone?  When I buy on eBay I can get a pretty good price and I read hundreds of real reviews from independent people.  If something is wrong, I know who they are and can dispute the transaction, etc.

Ive bought stuff from Scott ar Holybitcoin.com before and hes been great.  Id trust him 100% and hes always available to chat with on his website or gmail

^^^ This answer is the winner. 

[Sir_lagsalot]

Amazon, eBay, etc. But why would you want a miner? Just invest in cloud mining. Everything is taken care of.
