Privacy altcoins like Monero (XMR), Zcash (ZEC), and Firo (FIRO) use advanced cryptography. For example, ring signatures or zk-SNARKs. These make it almost impossible for regulators to trace transactions. So, what’s driving this crackdown, and which coins are at risk? In this video, I break down the most resilient privacy altcoins and how they work.
My first pick of today’s privacy altcoins is Monero ($XMR). This is also the most delisted coin globally. You can’t ask for a better intro, now, can you?
Monero doesn’t offer optional privacy. In contrast, it’s fully private by default. It uses RingCT and stealth addresses. RingTC is Ring Confidential Transactions. This is how Monero hides your transaction amounts. It does this by hiding transaction amounts. Monero also links senders and receivers using cryptographic ring signatures. This offers complete anonymity. It’s an improved version of its previous ring signatures feature.
Like with all privacy altcoins, this is great for our privacy. However, it clashes directly with AML/KYC obligations. These are the Anti–Money Laundering / Know Your Customer obligations. CEXes ask for these when you want to register. So, out of all today’s privacy protocols, Monero has the highest regulatory risk.
Monero has a censorship-proof peer-to-peer infrastructure. It’s actively maintained by one of the largest open-source privacy communities in crypto. It has an active dev base with plenty of contributors, with ongoing audits. This makes it today the most decentralized platform in this list. There’s no foundation or company.
Our generous community has recently funded a proposal for EVM atomic swaps development!
‘This proposal aims at developing a decentralized web application (dApp) to serve as a front end for the atomic swap smart contract. The web application will only require a web browser with…

Monero is also extremely censorship-resistant. As a result, it’s a common target of regulatory pressure. However, it’s technically very difficult to block at the protocol level.
The current Monero ($XMR) price is 318 with a $5.9 billion market cap. It has an unlimited token supply, which is not that great.
Zcash ($ZEC) is currently on the privacy altcoins list, the most popular one. Over the last 30 days, the $ZEC price has been up by almost 400%. That’s massive.
Out of today’s privacy altcoins, it’s the most “compliant” privacy coin. In other words, it’s safer legally, however, weaker technically.
Zcash supports two address types.
New feature announcement 📢

To achieve privacy, it uses zk-SNARKs. Those are the zero-knowledge succinct non-interactive arguments of knowledge. These validate shielded transactions without revealing sensitive info.
I expect ZK-SNARKs to be a significant revolution as they permeate the mainstream world over the next 10-20 years.

Zcash offers “viewing keys”. Users with a shielded address have options. They can share transaction details with auditors or trusted parties. That’s without giving up spending control. However, this remains a small fraction of total Zcash transactions in many periods. As of October 2025, around 27% of ZEC supply is held in shielded pools. This means that you can trace them by simple chain analysis. That’s over 4.42 million $ZEC.
Billions vanished after Friday’s crash. Projects without market makers collapsed overnight. Two days later, everyone acts like nothing happened. Over 27% of Zcash is now in shielded addresses

The current $ZEC price is $257 with a $4.13 billion market. There’s a max supply of 21 million tokens, with 16.3 million in circulation. $ZEC rallied hard, with privacy altcoins being in the spotlight. After such a parabolic run, a drawback is imminent.
Railgun ($RAIL) has been around since 2021 but hit the spotlight around a week ago. On October 9th it went parabolic. $RAIL went from $1.24 to $5.48 in only a day. That’s also a new ATH and a good 5x. The current $RAIL price is $4.11, and it’s 38% up on the day and 355% over the last 2 weeks.
In April 2024 it saw a similar surge. That was after Vitalik Buterin praised it on X. However, last week’s surge was stronger.
Privacy is normal.
Railgun uses the privacy pools protocol ( https://t.co/DekkatsMR5 ) which makes it much harder for bad actors to join the pool without compromising users’ privacy.https://t.co/MG0huDzpAu

This recent surge started after a post on X about the Kohaku wallet integrating Railgun. But that wasn’t all, it came with zk-multi signatures. Now, let that be a privacy feature that Buterin asked for. Oh yeah, Kohaku is an Ethereum Foundation wallet. So, a recipe for success, as the current $RAIL chart shows.
Many r getting excited that @ethereumfndn wallet Kohaku is @RAILGUN_Project integrated. Exciting for sure, but what has even more impact on private volume is the implementation of zk multisigs. Something Railgun has recently solved thanks to several overachieving developers. https://t.co/TRRCRbtltG

Railgun has Native EVM integration. There’s no need for bridges or separate chains. It works within existing chains and dApps. This offers private DeFi and token interactions. You can shield assets, interact privately, then unshield if you need to go back to a public address. It still has a low market cap of only $232 million. So, there’s plenty of room for growth.
No kyc. No bridges. No admin keys. Tip of the chain Ethereum privacy.

With Aleo ($ALEO) I have another small cap privacy coin on my radar. It’s built entirely for private computation, not just payments. Check out my recent video on Aleo. The link is here.
Aleo is a privacy-focused Layer-1 blockchain. It integrates zero-knowledge proofs (ZKPs) to enable private-by-default applications. This in contrast to traditional blockchains. These expose transaction details. However, Aleo ensures that sensitive information remains confidential. At the same time, it maintains transparency and security.
Aleo’s PoSW makes ZKPs faster & more efficient.

Its zk-SNARK approach allows for private transactions and smart contracts. Thus, ensuring that sensitive information is not exposed on the blockchain. However, it also introduces view keys. These allow you to decrypt your transactions for auditing purposes. This happens without compromising the privacy of others. This feature balances user privacy with regulatory compliance.
$ALEO is now listed on Binance Alpha!
With 280M+ users across 100+ countries, this listing brings Aleo to one of the largest global communities in blockchain.

In mid-September, $ALEO went live on Binance Alpha. The current $ALEO price is 25 cents. In early October, it shot from 22 cents to 42 cents. But as the chart shows, it’s almost back to its starting point. It has a $145 million market cap, so plenty of growth potential.
Firo ($FIRO) is the privacy coin with the smallest market cap today. It’s only $25 million. The current $FIRO price is $1.42. That’s 132% up from 2 weeks ago. So, it seems that Firo is riding the current privacy wave.
You may know Firo as Zcoin. It’s a privacy-focused coin that leverages advanced cryptographic techniques. With this, it provides you with enhanced transaction anonymity.
What sets Firo apart is its Lelantus mechanism. This allows you to burn coins, which are then anonymized within a large pool. You can later redeem these coins without revealing transaction links or amounts. This process ensures that transactions are unlinkable and untraceable. This provides robust privacy without the need for a trusted setup.
Lelantus Spark offers Spark addresses that are not searchable on the blockchain. Additionally, transaction amounts are hidden, further enhancing user privacy. This sets Firo apart from other privacy altcoins.
💡 Did you know? $FIRO uses advanced privacy protocols like Lelantus Spark to ensure your transactions stay completely anonymous. 🕵️♂️
No traces, no worries. That’s the power of Firo. 💥 #PrivacyCoin#Cryptopic.twitter.com/TR2DqJhqEK— Firo $FIRO (@firoorg) February 3, 2025
