What is Cryptojacks (CJ) Crypto Coin? The Full Story

Mar 9, 2026, Posted by: Ronan Caverly

When you hear the name Cryptojacks (CJ), you might think it’s just another altcoin trying to break into the crypto scene. But the truth is far more straightforward - and far less exciting. Cryptojacks isn’t a living project. It’s a ghost. A relic from 2016 that stopped moving years ago, with no trading, no updates, and no future.

What Cryptojacks Was Supposed to Be

Cryptojacks launched on October 24, 2016, with a clear goal: to be the go-to cryptocurrency for online gambling. Back then, blockchain-based casinos were still new. People were excited about the idea of provably fair games, instant payouts, and anonymous betting. Cryptojacks aimed to ride that wave. It wasn’t built on Ethereum or any smart contract platform. It had its own blockchain, using the X13 hashing algorithm - the same one Dash used - designed to be secure and resistant to ASIC mining. That meant regular PCs could still mine it in the early days.

The total supply was locked at 406,568,580.90842 CJ coins. No more could ever be created. That’s a fixed number. No inflation. No surprises. Sounds good on paper, right? But here’s the catch: no one ever built the ecosystem to make it useful.

Why It Never Took Off

Cryptojacks didn’t fail because it was poorly coded. It failed because timing and competition killed it.

By 2017, Ethereum-based gambling tokens like FunFair (FUN) and Edgeless (EDG) started appearing. These weren’t just coins - they were full platforms. Smart contracts handled game logic automatically. Players could verify fairness without trusting a casino. They had real communities, active developers, and listings on major exchanges. Cryptojacks? It had a website that went dark in 2019. No GitHub updates after October 2016. No Discord. No Twitter. No Reddit activity after 2018.

The gambling crypto space didn’t just move on - it left Cryptojacks behind. While FunFair hit a market cap of $35 million in 2023, Cryptojacks’ market cap hovered around $400,000 in early 2024 - and even that number is misleading. There’s been zero trading volume since October 15, 2019. Not a single CJ coin has changed hands in over four years.

The Numbers Don’t Lie

Let’s break down the facts:

Price: CoinMarketCap lists it at $0.0009827; LiveCoinWatch says $0.000083. Why the difference? Because no one’s buying. Prices are just guesses from tiny, outdated trades.
Market Cap: Around $399,540 on CoinMarketCap - but only because the circulating supply is multiplied by a price that hasn’t been validated by real trades in years.
Exchange Listings: Zero. Not on Binance. Not on Coinbase. Not on Kraken. Not even on obscure ones.
Wallet Activity: In late 2016, around 1,200 wallets held CJ. By 2018, that dropped to under 50. Today? Probably less than 10. Maybe none.
Blockchain Explorer: No integration with major explorers. It uses a strange "UCID 1306" identifier instead of standard addresses. That’s not a feature - it’s a red flag.

Is It Still Mineable?

Technically, yes. The X13 algorithm still exists. You could still run a miner. But there’s no point.

Mining pools shut down years ago. The original wallet software hasn’t been updated since 2016. If you download it now, it won’t sync with the network. Even if it did, you’d be mining coins with no buyers, no value, and no way to spend them.

And here’s the kicker: the website - cryptojacks.com - has been offline since at least July 2019. The Wayback Machine shows a broken, empty page. No downloads. No support. No hope.

A crypto graveyard with Cryptojacks' tombstone among glowing, active coins.

What Experts Say

Cryptocurrency researcher Alex Saunders called Cryptojacks a "zombie coin" in a 2020 report - a coin that’s technically alive but functionally dead. BitBoy Crypto’s Ben Armstrong called it out in his "Crypto Graveyard" series: "It was a niche token with no community, no updates, and no reason to exist once better tech came along." CoinGecko’s 2022 report put it bluntly: "Effectively zero network activity and no measurable community engagement." Messari’s 2023 report says tokens with zero trading volume for over three years have a 99.8% chance of permanent abandonment. Cryptojacks has been dead for more than five.

Should You Buy It?

No.

Not because it’s a scam. Not because it was a Ponzi. But because it’s already over. There’s no upside. No roadmap. No team. No exchange. No future.

Some people still hold CJ out of nostalgia. Maybe they mined a few coins back in 2016 and forgot about them. Others bought it on obscure exchanges during a hype spike, never realizing it was dead. But if you’re thinking of buying CJ now - even at a fraction of a cent - you’re not investing. You’re collecting a digital artifact.

Where Does Cryptojacks Fit Today?

Cryptojacks belongs in a museum. Not the kind with glass cases and plaques. The kind you find in a GitHub archive, a forgotten Bitcointalk thread, or a CoinMarketCap ranking at #6336 - buried under thousands of more active coins.

It’s a lesson. Not about how to build a successful crypto project. But about what happens when you build something for a market that moves faster than you do. When your website goes dark. When your devs disappear. When your community stops talking. You don’t get a second chance.

Cryptojacks (CJ) is not a coin you trade. It’s not a coin you mine. It’s not a coin you invest in.

It’s a coin that died.

A broken monitor showing '404' and outdated wallet with 'Last Commit: Oct 2016'.

What Happened to the Team?

No one knows. The founders were anonymous. No names. No LinkedIn profiles. No interviews. No press releases. After the initial launch, they vanished. No updates. No announcements. No explanations. Just silence.

In the crypto world, anonymity isn’t always bad. But when you disappear without a trace - and your project stops working - it looks like abandonment, not privacy.

Could Cryptojacks Come Back?

Theoretically, yes. Someone could fork the code, revive the blockchain, relaunch the website, and rebuild the community. But there’s zero evidence anyone’s trying.

No GitHub commits since 2016. No Discord activity. No Telegram group. No Reddit posts in six years. No news. No whispers.

In crypto, revival is rare. And when it happens, it’s loud. It’s backed by a team. It has funding. It has a roadmap. Cryptojacks has none of that.

It’s not a sleeper hit. It’s not a hidden gem. It’s a tombstone.

Final Thoughts

Cryptojacks (CJ) is a cautionary tale. It’s not a coin you should care about unless you’re studying the history of failed crypto projects. It has no utility. No liquidity. No future.

If you see CJ listed somewhere, don’t be fooled by the price. That number is meaningless. There’s no market. No buyers. No sellers.

The only thing left of Cryptojacks is its name - and even that’s fading.

Is Cryptojacks (CJ) still being traded?

No. Cryptojacks has had zero trading volume on any major exchange since October 15, 2019. All platforms, including CoinMarketCap and Binance, report $0 in 24-hour trading. The price you might see online is based on outdated, isolated trades - not real market activity.

Can I still mine Cryptojacks today?

Technically, yes - the X13 algorithm still exists. But there are no active mining pools, no updated wallets, and no way to sync with the blockchain. Even if you mine a coin, you can’t send it or sell it. Mining CJ today is like building a car with no roads to drive on.

Is Cryptojacks listed on Binance or Coinbase?

No. Neither Binance nor Coinbase lists Cryptojacks. Binance explicitly states it is "not listed for trading and services." Coinbase has never supported it. You won’t find CJ on any major exchange.

What was Cryptojacks used for?

Cryptojacks was created as a cryptocurrency for online gambling platforms in 2016. It was meant to be used for betting on games like dice, poker, and slots. But it never gained traction because better, Ethereum-based alternatives like FunFair launched shortly after, offering smart contracts and provably fair systems.

Why did Cryptojacks fail?

It failed because it had no active development, no community, and no exchange support after 2018. Its website went offline in 2019. The team disappeared. Meanwhile, competitors built better, transparent gambling platforms on Ethereum. Without updates or users, Cryptojacks became obsolete.

Can I recover my Cryptojacks coins if I still have them?

You can still access your wallet if you have the private keys - but there’s nowhere to send the coins, no exchange to sell them, and no value attached to them. They’re essentially digital collectibles with no utility. There’s no recovery path because there’s no active network to interact with.

Wow, so Cryptojacks is just a digital ghost story now? I love it. This is why I don't trust any crypto that doesn't have a meme coin version of itself. If it's not chaotic, it's dead. I'm starting my own coin called 'ZombieBucks' - it'll be mined by AI ghosts in a metaverse graveyard. Pre-sale starts Tuesday. Send BTC or GTFO.

Honestly, this breakdown is spot on. Cryptojacks wasn't evil - it was just outpaced. The real tragedy isn't that it died, it's that no one learned from it. Most new projects still think 'launch a blockchain + whitepaper = success.' They don't get that community and iteration matter more than algorithmic elegance.

The data here is terrifyingly accurate. Zero trading volume since 2019? That's not a dead coin - that's a tombstone with a price tag. People still check CoinMarketCap like it's a live ticker. It's not. It's a hallucination. If you're holding CJ, you're not an investor. You're a curator of digital archaeology.

Ah, yes. Another American crypto graveyard. In India, we call this 'beta version of capitalism.' You build something beautiful, then vanish because the market moved on. We have a phrase: 'Jab log chalte hain, toh ek hi aadmi rukta hai.' When everyone walks, only one man stands still. Cryptojacks was that man. And now? He's a statue.

BINGO. This was a FedCoin op all along. I told you. The 'anonymous team'? They were CIA contractors. The blockchain? A honeypot to track early adopters. The 'dead' wallet addresses? They're all tagged. You think no one's watching? HA. The real coin is the data they harvested. CJ was never meant to be money. It was meant to be a surveillance net. And now? They're using it to predict your next crypto purchase. 🕵️‍♂️

I must say, this post exhibits a commendable level of factual rigor. However, one must interrogate the underlying epistemological assumption: that 'value' is contingent upon market liquidity. This is a capitalist fallacy. Cryptojacks, as a symbolic artifact, possesses intrinsic historical value - a monument to the hubris of early blockchain idealism. One does not 'invest' in a fossil. One reveres it.

I've been mining CJ since 2017. I still have 8,000 coins. I don't care if they're worthless. Every time I open my wallet, I remember the early days. The forums. The Discord. The guy who said 'this is the future' and then disappeared. I keep them because they're the last proof I ever believed in something. Not because I think they'll rise. Because I need to remember that I once did.

The real story isn't Cryptojacks. It's that we keep digging up dead coins like they're buried treasure. We're not investors. We're grave robbers. Every time someone says 'maybe it'll rebound' - they're not hoping for profit. They're hoping for closure. And that's the saddest part. We're not chasing returns. We're chasing ghosts.

bro i just mined 200 cj coins last week on my old laptop 😅 i thought it was still live. then i checked the explorer and it was like a dead server. i felt bad for the devs. like they built something beautiful and just… forgot to turn the lights off. maybe they got sick. maybe they died. maybe they just got bored. either way, we should keep the blockchain running. just for them.

I used to gamble on Cryptojacks sites. I lost like $200. I didn't even know it was dead. I just kept checking the app. It still showed my balance. I thought I was rich. Then one day it just… didn't load. I didn't cry. I just laughed. Sometimes the universe gives you a lesson in humility. This was mine.

If you're still holding CJ you're either a masochist or a historian. There is no third option. The fact that CoinMarketCap still lists it is an insult to rationality. It's like including a 1998 Nokia 3310 in the smartphone market cap report. It's not a coin. It's a museum piece. And museums don't trade.

I used to run a small mining pool for CJ. We had 12 people. We didn't care about the price. We cared about the tech. The X13 algo was elegant. Simple. Efficient. It wasn't about making money. It was about proving you could build something decentralized without Ethereum. That’s why it died. We didn't want to be part of the hype. We just wanted to build. And now? No one remembers why we even tried.

I think about Cryptojacks like a first love. You don't forget it. Not because it was perfect. But because it was real. You believed in it. You stayed up late mining. You told your friends. You felt like you were part of something new. Then it vanished. And you never got to say goodbye. That's the real tragedy. Not the price. The silence.

The technical architecture of Cryptojacks was fundamentally sound. The X13 algorithm, while not ASIC-resistant in the long term, offered sufficient decentralization for its era. The failure was not algorithmic but sociotechnical: absence of governance mechanisms, no formalized upgrade path, and complete neglect of user onboarding. In blockchain terms, it lacked a viable incentive layer beyond mining rewards - which collapsed when liquidity evaporated.

I know who took them. The ones who made CJ. They didn't disappear. They got scared. They saw what happened to other anonymous teams. The doxxings. The lawsuits. The death threats. They knew someone would trace the coins. So they buried the blockchain. They erased the website. They deleted the keys. And now? They're living in a cabin in Alaska. Watching the world trade fake ghosts. And they're laughing. Because they're the only ones who know the truth: the coins were never meant to be mined. They were meant to be erased.

Don't buy it. Don't mine it. Don't even look at it. It's not a scam. It's worse. It's a trap for the nostalgic. You think you're getting a bargain. You're not. You're buying a tombstone with a price tag.

There's a quiet beauty in something that dies cleanly. No drama. No fraud. No pump. Just silence. Cryptojacks didn't go out with a bang. It just… stopped. No announcement. No farewell. No final tweet. It just became a footnote. And maybe that’s the most honest way to go. Not every project deserves a funeral. Some just deserve to be forgotten.
