On a quiet night in July, when most people were asleep, something big was happening in India’s cryptocurrency world.

Between 3:30 AM and 4:00 AM, hackers attacked the servers of Coin DCX, which is one of India’s major centralized crypto exchanges, and took away about 370 crores, which is around $44. 2 million worth of digital assets.

Wait, what?

Did that really happen?

Yes. And what makes it even more surprising is how the whole event happened — quietly, without any official announcement from Coin DCX at first.

The first person to sound the alarm wasn’t a news organization or a company’s public relations team. It was Z_XBT, a well-known person in the crypto investigation world — the same person who uncovered Melon Lam just a month ago.

He posted on his Telegram channel saying that a possible $44.

2 million hacks had taken place on Coin DCX almost 17 hours before, but there was no public statement made about it.

The Silence Before the Storm

Independent researcher Z_XBT was the first to raise the alarm about the Coin DCX hack — nearly 17 hours before official confirmation.

After Z_XBT raised the alarm, things became more serious.

Eventually, Sumit Gupta, the CEO and co-founder of Coin DCX, shared an official message on social media.

In a video, he confirmed the security breach, saying:

“Today, one of our internal operational accounts, which is only used for providing liquidity on a partner exchange, was hacked because of a complex server attack.

I want to make sure you know that the Coin DCX wallets used to hold customer money were not affected and are still fully secure. “

He stressed the importance of being open and clear, adding that no user funds were at risk, and the breach only involved an internal account.

The Investor Panic Begins

As soon as Sumit confirmed the hack, panic started spreading quickly.

Investors hurried to take out their money — not just because they wanted to, but because the fear of losing their hard-earned crypto was stronger than anything else.

After the Wazir X hack earlier this year, where many users either didn’t get their money back or only got part of it, trust in Indian exchanges has become very weak.

Even though Coin DCX said the stolen funds were the company’s own and not customers’ money, the community wasn’t ready to take risks.

Withdrawals increased a lot.

I personally tried to withdraw my funds, and it worked fine without any problems.

But on social media, people had mixed feelings — some said there were delays, while others praised Coin DCX for handling the process smoothly.

The Unintended Tax Trap

Here’s the issue most people didn’t think about at that moment.

Imagine you had invested 1 lakh rupees in cryptocurrency during a strong market trend and were planning to hold onto it for 5 to 10 years.

But then, because of fear, you decided to sell your crypto and take the money out in rupees to keep it safe.

Suddenly, you created a taxable situation.

Even if you didn’t mean to sell, once you changed your crypto into cash (rupees), you have to pay a flat 30% tax on any profit you made.

This sudden decision caused many people to accidentally create tax obligations — a hard lesson for long-term investors who never intended to leave the market.

What About the Exchange’s Stability?

Let’s step back and think clearly. ₹370 crores are a massive amount. Some people thought maybe the hack was an inside job — maybe the management created it to move funds secretly.

But does that make sense?

Coin DCX is worth about $2.

15 billion, which is roughly ₹20,000 crores.

Would a founder or management team of a ₹20,000 crore company risk everything for just ₹370 crores?

That seems very unlikely.

While anything can happen in the crypto world, this idea doesn’t seem strong to me.

The amount at risk is way too small compared to the company’s total value.

Also, the way the team responded — quickly admitting the hack, reassuring users, and keeping trading and withdrawals running — shows they are experienced and capable.

A Glimpse of Opportunity Amidst Panic

Interestingly, the confusion during the rush to sell led to a chance for some people.

During the sudden withdrawals, USDT (Tether), which usually trades close to ₹83–84, fell as low as ₹78 on Coin DCX.

That’s more than 5% below its supposed value.

A few clever traders noticed the drop, bought USDT at a lower price, and made money when the value went back to normal.

One trader told me late at night that he was surprised to see USDT trading 10% lower.

He bought it, waited for the price to return to its usual level, and made a quick profit.

Other crypto pairs like Ethereum also dropped sharply but only temporarily, bouncing back soon after.

For some, it was a stressful moment, but for others, it was a chance to make money.

The Bigger Picture: Crypto Exchange Security in India

This hack shows again how even the best crypto exchanges are not safe.

Even with strong security measures, hackers are now very skilled.

As long as money is kept online, there will always be some risk.

That’s why cold wallets — which are not connected to the internet — are very important.

Coin DCX said all user funds were kept in cold wallets, which helped protect customers’ money.

We shouldn’t forget that Coin DCX isn’t the only big exchange that’s been hacked this year.

Around the world, exchanges like By bit lost over $1. 46 billion in one attack.

Coin base also had a $400 million hack in May. Hacks are happening more often, are more organized, and are causing bigger losses.

In India, the only major exchange that’s often mentioned for not paying back users after a hack is Wazir X.

Coin DCX, on the other hand, has kept all its funds available and allowed users to withdraw without any problems, which helps build trust.

What Happens Next?

Right now, Coin DCX is running normally. Trading is happening as usual.

Withdrawals are going through without problems.

The worry among investors has gone down.

But there are still questions.

How did the security breach happen?

Which parts of the system were attacked?

And how can we stop something like this from happening again in the future?

More importantly, this is a reminder for every crypto exchange and user in India.

Security should be the number one concern.

Exchanges need regular checks, reward programs for finding bugs, and strong security measures.

And for users, we should never keep all our money in one exchange or one wallet.

Final Thoughts

The ₹370 crore hack on Coin DCX marks a significant moment in India’s crypto journey.

It put the trust of thousands of users to the test, caused a temporary shake in the market, and highlighted both the weaknesses and resilience of our system.

Coin DCX acted swiftly and openly, without stopping trades or restricting withdrawals, and fully admitted what had happened.

However, it also revealed deeper concerns — like the fear of unexpected losses, worries about unclear rules from regulators, and the feeling of being controlled by big platforms.

As the crypto world grows, so do the risks. The way forward is more knowledge, better safety measures, and ongoing improvements.
