Is mining with Antminer S9 still worth it?

I am interested in starting to mine bitcoin. I found a local ad selling a couple Antminer S9 computers and am unsure if mining would be feasible under these conditions. I'm also interested in mining different types of currencies, but can't figure out if it's even possible to mine most currencies, and further if I'd get a potentially better return from just buying in at <$1 per coin prices. I want to diversify and have a wide ranging coin portfolio, and figured mining was the best, cheapest, and most lucrative way to do this. Can anyone advise otherwise?
Here's the local ad selling the Antminer..Is this legit? Would it be a good price? https://newyork.craigslist.org/brk/ele/d/start-your-bitcoin-mining/6238008470.html
Thanks in advance for the help!

Where can I buy old ASICs? Currently looking for a Rockminer R-Box or similar

I'm building a bitcoin miner on a raspberry pi as a project with my son (yes - I understand fully I'll never earn a cent... er, satoshi).
My previous experience with mining was using a Rockminer R Box, and I was wondering if anyone has an old one or something similar they wouldn't mind parting with. I'm happy to buy it, if needed.
Basically, all the sellers I'm seeing on Craigslist and Ebay and so forth are advertising even the old USB 333 MH drives at over $50 - ridiculous markups that I suspect are preying on people who don't know any better and are trying to get in the mining game. Since none of these miners will ever earn money, its pretty ridiculous to sell them at those rates...
I like the R box as they were pretty silent and didn't make the house too hot (like my old antminers) and I want something a little more complex than a simple USB drive to put together with him.
Basically, we are going to put it together, learn about mining, then leave it on solo mining to try it as a bitcoin lottery.
Anyone know a good market for old miners - or have an old one they'd sell at a reasonable price?
Note to mods: not a "for sale" post - Its a want ad if anything :)

How to earn Bitcoin?

Overview - Table of Contents Introduction to Earning in Bitcoin Work for Bitcoin Sell for Bitcoin Affiliate Programs Gambling Bitcoin Mining Hardware Mining Cloud Mining Introduction to Earning in Bitcoin Bitcoin is the most popular digital currency in the world today. Bitcoin cloud mining is the fastest way to immediately begin earning bitcoins. Bitcoin is built using very complicated cryptographic principles, and supported by countless individuals and companies from all around the world. By early 2016, total Bitcoin market capitalization had crossed USD 7 Billion, making it almost as valuable as the GDP of a small country like Bahamas. All the other digital currencies together do not constitute even 20% of Bitcoin’s market capitalization, underlining the its dominance and importance in the world of digital currencies.
With such a huge amount of world’s capital available in the form of Bitcoins, the number and types of opportunities to earn in bitcoins are increasing by the day. In this article we will discuss such opportunities that help us earn bitcoins.
We will start with the easiest, or the one that is applicable for the maximum number of people, and then move to the tougher ones. In the end we will cover earning bitcoins by mining. Bitcoin mining is not an easy way to earn bitcoins, but we do have a number of easier ones we will discuss first. So lets start with ‘earning bitcoins by offering your services’
Work for Bitcoin Perhaps the easiest way to earn bitcoins is to work online or in real life for bitcoins. Because of the huge size of the bitcoin eco-system, a number of such opportunities and jobs are available. With Billions of dollars invested in Bitcoin by tens of thousands of people, there is a real market in Bitcoin, where you can find jobs for freelancers, software developers, writers, and others who get paid in bitcoins for their services.
Software development, writing, design, making websites or apps, audio transcription, are some of the most active types of jobs. You can easily discover the types of jobs by going over the more popular job boards for bitcoin related work. The following job boards or forums are some of the best places to look for such jobs or gigs.
Freelancing
XBTfreelancer Cryptogrind Bitlancerr Coinality Bitgigs Jobs4Bitcoins Rein Project Crypto Jobs List Market Places
OpenBazaar Purse.io Bitify /bitmarket 21 Market Video Streaming
Watchmybit Streamium.io Tasks
Bitasker BitforTip WillPayCoin File/Image Sharing
Supload.com SatoshiBox JoyStream Advertising
CoinAd A-ads Coinzilla.io Also, check BitcoinGames for ideas on earning bitcoin and blockchain game assets.
Sell for bitcoin You can also get Bitcoin by selling your old laptops, phones or other items for Bitcoins. Such types of transactions are happening more and more, and a lot of buyers are already buying anything from iPhones to even cars by paying with Bitcoins. For Americans, Craigslist.com is your best bet when you want to find such buyers. You can mention in your ad that you are willing to take payment in Bitcoin. This way if anyone wants to buy the item for you for Bitcoin, they can contact you and make an offer. The same principle applies to other online marketplaces such as gumtree for UK, kijiji for canda etc.
Affiliate Programs Affiliate programs allow a promoter of a business or product to earn money or bitcoins by refering new clients to such businesses or products. For example, amazon.com has a popular affiliate program, where you can earn commission ranging from 2% to 20% for refering clients to products listed on amazon.com. Amazon normally pays in dollars, but there are a number of other sites and businesses which pay you in bitcoin for acting as their affiliate.
Some of the more popular affiliate programs that pay out in Bitcoin are by the sites: cex.io, coinbase.com, okcoin.com and namecheap.com, among others. You can find a larger list of such affiliate programs on the bitcoin wiki page for Affiliates.
Gambling We do not recommend gambling for every player or every user; we find that gambling is only suitable for people who know how to win at it. However, if you are one of such lucky users who have some tricks up their sleeves, and can manage to win at games such as poker, then you will find that earning bitcoins is not that hard.
One of the many applications of bitcoin since the very beginning have been in betting games or gambling. Because of the relative anonymity of bitcoin, and the lower fees, it is very suitable for gambling related applications. Indeed, one such game, satoshiDICE, has been running since 2012, and has paid out a huge number of bitcoins in innumerable transactions to its winners. There are many such games, which you can find be googling.
If you want to gamble totally anonymously, you can play gambling or betting games that are available only on darknet or .onion sites. Such sites allow you to browse them anonymous by operating on the tor network, which is a secure network that allows users to browse .onion websites without exposing their own IP address.
Bitcoin Mining For each block that is added to the Bitcoin Blockchain, a number of bitcoins are rewarded to the creater of that block. This reward is currently, as of June 2016, 25 bitcoins per block, and it halves every four years. The next halving will be in July 2016. Creating or finding the new blocks, and therefore winning the reward of 25 bitcoins for each block you create, is called bitcoin mining. To do bitcoin mining successfully, you need very powerful computers, which compete with other computers to find the next block. The speed or power of computer that do bitcoin mining is calculated in hashes calculated per second.
There are two ways to do bitcoin mining: one is to own hardware or computers that do the mining, and second is to hire the hardware from a third party, usually online, and do the mining on the cloud. Let us discuss the advantages and disadvantages of both in next two sections.
Hardware Mining When you own the hardware that does the calculations and mining of bitcoins, its called hardware mining. Hardware mining is the more popular or prevalent of the two types of mining we mentioned. One of the biggest factors which comes into play when doing bitcoin mining using your own hardware is the price of electricity. If you pay top price for electricity, then bitcoin mining may not be your cup of tea. Another related factor is infrastructure needed to cool the hardware; since every cpu generates some amount of heat, you may need to cool the hardware in case they become too heated. No wonder that some of the most successful miners work from China, specially Tibet, where they can get cheap electricity, and their cooling costs are low due to high altitude which reduces the ambient temperature for them.
For a more in-depth information on how to setup your hardware mining equipment, have a look at the Antminer setup page.
Currently, based on (1) price per hash and (2) electrical efficiency the best Bitcoin miner options are:
AntMiner S7 AntMiner S7 Bitcoin Miner 4.73 Th/s 0.25 W/Gh 8.8 pounds Yes $479.95 AntMiner S7 Bitcoin Miner 0.1645
AntMiner S9 AntMiner S9 Bitcoin Miner 13.5 Th/s 0.098 W/Gh 8.1 pounds Yes $1,987.95 AntMiner S9 Bitcoin Miner 0.3603
Avalon6 Avalon6 Bitcoin Miner 3.5 Th/s 0.29 W/Gh 9.5 pounds No $499.95 Avalon6 Bitcoin Miner 0.1232 Cloud Mining There are a number of service providers that allow you to rent computational hardware from them, which can then be used to do bitcon mining. Some of these services are designed with bitcoin mining in mind, whereas others such as Amazon AWS are general purpose services that can also be used to do bitcoin mining.
Some of the cloud mining services which can be used to do bitcoin mining on the cloud are:
Hashflare Review: Hashflare offers SHA-256 mining contracts and more profitable SHA-256 coins can be mined while automatic payouts are still in BTC. Customers must purchase at least 10 GH/s.
Genesis Mining Review: Genesis Mining is the largest Bitcoin and scrypt cloud mining provider. Genesis Mining offers three Bitcoin cloud mining plans that are reasonably priced. Zcash mining contracts are also available.
Hashing 24 Review: Hashing24 has been involved with Bitcoin mining since 2012. They have facilities in Iceland and Georgia. They use modern ASIC chips from BitFury deliver the maximum performance and efficiency possible.
Minex Review: Minex is an innovative aggregator of blockchain projects presented in an economic simulation game format. Users purchase Cloudpacks which can then be used to build an index from pre-picked sets of cloud mining farms, lotteries, casinos, real-world markets and much more.
Minergate Review: Offers both pool and merged mining and cloud mining services for Bitcoin.
Hashnest Review: Hashnest is operated by Bitmain, the producer of the Antminer line of Bitcoin miners. HashNest currently has over 600 Antminer S7s for rent. You can view the most up-to-date pricing and availability on Hashnest's website. At the time of writing one Antminer S7's hash rate can be rented for $1,200.
Bitcoin Cloud Mining Review: Currently all Bitcoin Cloud Mining contracts are sold out.
NiceHash Review: NiceHash is unique in that it uses an orderbook to match mining contract buyers and sellers. Check its website for up-to-date prices.
Eobot Review: Start cloud mining Bitcoin with as little as $10. Eobot claims customers can break even in 14 months.
MineOnCloud Review: MineOnCloud currently has about 35 TH/s of mining equipment for rent in the cloud. Some miners available for rent include AntMiner S4s and S5s.

11-16 22:23 - 'Is mining worth it anymore?' (self.Bitcoin) by /u/cye604 removed from /r/Bitcoin within 21-31min

'''
I found a local guy on Craigslist selling his Antminer D3 for a few hundred dollars, and I might jump for it. From doing some looking online, it seems that Bitcoin mining with it would net me a whopping 30 cents a month equivalent, while NiceHash estimates that mining other currencies can net around $5 per day.
Is this trend going to continue? Will it continue dropping until eventually, mining is not worth it anymore unless you are in the 20+ TH/s range?
It seems to me that bitcoin is more of a stock now than a resource. You buy and sell what already exists, instead of making your own.

Antminer U3 for 50$ in Switzerland?

I've found a used Antminer U3 for 50$ on the Swiss version of Craigslist.
I have no experience with mining bitcoins and am wondering if this is a good place to start. From what I gather there are a lot of factors that play in if mining is profitable or not. Here in Switzerland we have quite high costs for electricity (25 cents per kilowatt). Combine this with a miner that can only do 60 Gigahashes, would this be profitable at all?
