tldr; The Cardano blockchain experienced a chain split due to a malformed transaction exploiting a software flaw, causing network disruption. The incident, described as a 'poisoned' transaction attack, led to two distinct chains forming. Developers coordinated an emergency response, urging node upgrades to restore the main chain. The responsible individual apologized, claiming no malicious intent. No user funds were lost, but ADA's price dropped over 6%. Authorities, including the FBI, are investigating the incident as a potential cyberattack.

Just to clarify, ISO20022 is not a blockchain protocol or consensus mechanism, it’s a messaging standard.
[https://youtu.be/hdLjIVlA\_DA?si=hZPNstwmL7cAR0J8&t=1400](https://youtu.be/hdLjIVlA_DA?si=hZPNstwmL7cAR0J8&t=1400)
Chainlink worked directly with swift on ISO20022 to include blockchain components to it and sections of the standard related to blockchain. This means chainlink has infrastructure (CRE) that can listen to iso20022 messages sent via Swift and can then trigger on chain actions, [seen here](https://www.coindesk.com/business/2025/09/30/chainlink-ubs-advance-usd100t-fund-industry-tokenization-via-swift-workflow).
*"In a pilot with UBS, Chainlink’s Runtime Environment (CRE) processed subscriptions and redemptions for a tokenized fund using ISO 20022 messages, the international standard for financial messaging used by Swift."*
So what does mean for your shitcoin that claims to be iso20022 compliant? Well being “iso20022 compliant” just means that a system can format messages in a way consistent with that standard. It doesn't give you access to Swift or guarantee interoperability with Chainlink’s infrastructure.
And what does this mean for chainlink? Well, it positions Chainlink as the backbone for bridging traditional finance (banks + Swift) with on chain tokenized assets in a standard compliant way.
Heres the fake ISO20022 list but just because youre integrated doesnt guarantee them anything.

A common mistake people buying altcoins make is that thinking that just because a project has a real team and a technical white paper and purport to solve some problem doesn’t mean it’s a good investment. More important is to demonstrate product market fit. You can evaluate that by looking at metrics like revenue, users, volume, TVL, etc.
The crypto graveyards are littered with altcoins that purported to have the best tech but nobody ever used them. Especially for L1 chains. Just look at the top 20 coins from 2018 or 2021. ALGO, VET, NEAR, XLM, ADA, HBAR, DOT, ICP, ATOM, IOTA, NANO, etc.
Only ETH, SOL, and BNB gained any significant market share the rest failed.
That’s what people mean by alts dying off each cycle. All of those cryptocurrencies were massively hyped and none gained any real traction with users or developers.

This is easy to demonstrate. Just look at alt/btc and alt/eth charts over the last few years. Most of them are flat, some are oscillators, few are rising...
My ADA, LINK, DOGE, BONK are all 😔

Honestly. Nobody really knows. I don’t subscribe to buy and hold with crypto because it has no intrinsic value.
I do buy on the dips of 8% and above weekly and then in 2-3 weeks sell at a profit of 15-20% gains for the week.
Since May I've more than tripled my initial investment of $5000 doing this on XRP, DOGE, HBAR, TRON, and ADA.
Robinhood and Kraken (I'm sure others do too) make this easy to set buy and sell limit orders so you don't have to constantly watch it.
I've bought $12k of the above this week and because the losses have been so great, I've raised my "sell" percentage to +15% on $8k and +25% on the remaining $4k as the top 10 players are off over 30% average on their all time high.
So even if I miss the mark on my 25% I'll still make excellent returns on my 15% targets.
The key is being patient, don't panic and don't get greedy on your expected returns...8-10% return in a 30 day period is 96-120% annual return rate!

XMR will def recover. ADA? XRP? Maybe

I see a lot of things actually happening with XRP and their CEO “working” with government officials etc, they’ve been posted about by the president just like SOL, BTC, ETH, ADA. etc… Genius Act this Clarity Act that…. Lawsuit is over…. What’s the deal? Are people really getting jipped out here or does nobody really know? Idk. Just seems weird people rip into other peoples souls on Reddit when they find out someone invested in XRP. Often times they say “anything but XRP” I guess I’m just curious idk. The hate for that one is stronger than any other crypto IMO. Thoughts?

>Main cryptos (BTC, ETH, XRP, ADA, etc) will certainly recover from this bear market
I bet people said that about NEO, NEM or whatever coins we had in 2017

Okay, I was in the same situation some years ago.
SO first question is: DO YOU NEED THIS MONEY RIGHT NOW?If the answer is "Yes": Sell now, and stop losing. It sucks, but if you need the money, accept your loses and carry on.
Let's say you DON'T need the money right now. What to do?
**HOLD.**
I'm not a guy of "hodl" no matter what. Let me explain: Back in 2021 BTC reached 65k give or take. I sold, made profits. OH YEAH!. Then it dipped to roughly 60K, I bought again thinking (among other coins) thinking prices would keep rising...
And well, they crashed. My wallets were at -80% benefit.
So I decided to let it be. At the end of 2024 I started seeing some greens in my profits.
And just a few months ago I sold to stablecoins, recovering my whole investment and getting profits.

**SO WHAT'S MY ADVISE?**
Well, I moved away from ALTs long ago. They are like chasing a golden goose. Main cryptos (BTC, ETH, XRP, ADA, etc) will certainly recover from this bear market, but it may take time.
You need the money? Sell now and don't lose more.
You don't need the money right now? Wait. It may recover. Or not.
**Never invest money you can't afford to lose!**

I don't sell Bitcoin at all and my ETH and ADA I'm still up from my dollar cost average.

The cardano network is down , you can't close position or transfer ADA ...

I'm buying, man. I'm still up on my investments this cycle with BTC, ETH and ADA. I added a bit to my BTC but buying a lot of ADA right now.

I held ADA since 2021 and DCA along the way. I ended up with 25k ADA at an average cost of like .65. Three weeks ago I realized it wasn't going anywhere. I sold it all at a lost. Glad I did.

For My advice for newcomers on Cardano is always the same:
germans, use Eternl Wallet, german company, german guides.
For english, use VESPR, fastest wallet, easy to use, perfection on its own.
Never use overstaturated Pools, everything above 80% won't get you as much rewards as below this threshold.
Pledge of the SPO is NOT relevant (I pledge 1ADA and get blocks nearly every epoch).
If you have a small amount like under 1k ADA, you can maximise your rewards with a pool that has 170ADA fixed cost and is around 1M delegated.
If there are any questions: I build a guide on my website to walk you through every step.

I felt like I was reading my story. Started near end of 2020, was Up 80% overall before crash of 2021 and now I am down 60% in total value. Surprisingly, only XRP is the one I am in green. ADA, Atom, Dot, Vet, Algo and many more shit, I am down.

**Hey guys, I’ve built a small thing :) (one-man project, self-taught, just a Cardano enthusiast trying to contribute to the ecosystem).**
Wanted to share something NFT-related I’ve been experimenting with — a simple fully on-chain messaging dApp called **matotam.io**.
Every message you send becomes an **NFT**:
* text stored in metadata
* tiny SVG render
* and \~1.5 ADA locked inside the NFT (minUTxO)
The fun part:
**That ADA is refundable.**
Whoever burns the NFT — sender or receiver — gets the locked ADA back.
So messages are basically little "reclaimable NFTs" you can send to any wallet.
Total cost per message is around \~2.5 ADA (minting + network + small dev fee), with \~1.5 ADA being reclaimable later.
There’s no backend at all — everything runs through CIP-30 + Lucid, purely client-side.
Just wallet → chain → wallet.
**Why share it here?**
Because it’s essentially a *utility NFT*, but without a project behind it — just a simple mechanism anyone can play with
A few more or less serious use cases can be found in the picture ;)
