It started with a text: “Just invest 0.05BTC and watch it double in 24 hours!” Charles, a curious newbie in crypto, clicked the link. Weeks later, his funds vanished along with the scammer. He had just met Bitcoin’s dark side: the Ponzi scheme. But he wasn’t the first victim.
In 2023, crypto scams drained over $5.6 billion, with Ponzi schemes leading. If that sounds bad, 2022 was worse: $7.8 billion disappeared into crypto Ponzi and pyramid schemes, many using Bitcoin as bait.
Bitcoin has changed lives, but it has also opened doors to new-age fraud. Let’s uncover the biggest Bitcoin Ponzi schemes ever, and how to avoid becoming the next victim.
What Is a Crypto Ponzi Scheme?
A Ponzi scheme is a scam that pretends to be a real investment but pays earlier investors using money from new ones instead of actual profits. There’s no real business behind it, just a cycle of recycling cash until it all falls apart.
Think of it like this: you give me 100 BTC because I promised to invest it in some secret magic strategy. Then I take 100 BTC from the next person and use their money to pay you returns. Rinse and repeat until the whole thing collapses. By this time, I’ve pocketed enough and vanished.
That is a Ponzi scheme. In crypto, it just wears flashier clothes.
Instead of bank accounts and official records, crypto Ponzi schemes use slick websites, made-up tokens, and fake trading bots. They dress up as “staking platforms,” “automated AI systems,” or “next-gen blockchain revolutions,” but the pattern is always the same: rob Peter to pay Paul.
It is easy to market these unrealistic profits, especially to people who don’t fully understand how crypto works. And because legitimate crypto investments can offer high returns, scammers use just enough truth to make their lies convincing.
Biggest Bitcoin Ponzi Schemes in History
Crypto scams get cleverer by the day, but some stand out for their scale, shamelessness, and huge losses. Here are the biggest Bitcoin Ponzi schemes ever exposed, from the most recent to the most notorious:
1. Mirror Trading International (MTI) (2019–2020)
MTI sold the illusion of AI-powered Bitcoin trading. No such thing existed. Instead, they shuffled funds between investors. It posed as a genuine South African-based platform and roped in around 100,000 users across 140 countries. It eventually collapsed with under $589 million in losses. A U.S. court later ordered $1.7 billion to be paid to the victims.
2. PlusToken (2018–2019)
PlusToken promised 10–30% monthly returns through a mobile crypto wallet. It pulled in over 4 million users, primarily in Asia, and ran off with an estimated $3 billion before the scam unraveled. Chinese authorities eventually arrested the major founders, but most investors never saw their Bitcoin again.
3. GainBitcoin (2015–2017)
Launched in India, GainBitcoin marketed itself as a cloud mining solution offering 10% monthly returns for 18 months. This scheme convinced thousands of investors and attracted over $300 million without having any real mining operations behind it. The scheme collapsed in 2017, and the founder, Amit Bhardwaj, was arrested in 2018, but the money was never recovered.
4. OneCoin (2014–2017)
OneCoin sold itself as the next Bitcoin, but there was one major problem: there was no blockchain. Instead, it peddled fake tokens with glossy educational packages and used multi-level marketing to spread across over 175 countries.
The result? This was a massive $4 billion Ponzi scheme that defrauded around 3.5 million investors, making it one of the greatest crypto scams of all time.
Founder Ruja Ignatova, now known as the “Cryptoqueen,” disappeared in 2017 and is currently on the FBI’s Ten Most Wanted list. Her co-founder, Karl Greenwood, was not as lucky. He was arrested, convicted of wire fraud and money laundering, and then sentenced to 20 years in prison in 2023.
5. BitConnect (2016–2018)
BitConnect might be the most infamous crypto scam of them all. It promised users 1% profit daily through a so-called trading bot that was supposed to grow your money magically. But behind the scenes, there was no bot. New users’ funds were used to pay earlier ones.
At its peak, BitConnect became one of the top 20 cryptocurrencies in the world, with a market value of around $3.4 billion. But when regulators started investigating in early 2018, the whole thing crashed. The BCC token dropped by over 90% in a few days, and investors lost billions.
U.S. authorities later revealed that BitConnect’s founders had collected more than $2 billion worth of Bitcoin from thousands of people worldwide. The platform’s founder, Satish Kumbhani, was charged in the U.S. for running one of the biggest crypto Ponzi schemes in history.
Each platform used Bitcoin’s legitimacy as bait, pairing slick marketing with fake tech, but under the hood, they all used the same method: steal from the new to pay the old.
How to Avoid Falling Victim to Bitcoin Ponzi Schemes
Not all that glitters in crypto is gold. Ponzi schemes have evolved, but the red flags remain the same. Here’s how to protect your Bitcoin and avoid becoming another victim:
1. Beware of Guaranteed Profits
If someone promises you daily, weekly, or fixed returns like “Earn 10% a month with zero risk!” run. Real crypto markets increase, and no legitimate investment guarantees profits.
2. Don’t Trust Tech Terms Blindly
Scammers love to use tech terms like “AI trading bot,” “staking platform,” or “next-gen blockchain.” Always ask what it does and if anyone can verify it. It is a red flag if it sounds too complex to explain or if only insiders understand it.
3. Be Wary of Referral Promises
If you’re being asked to invite friends and family to earn more, it’s likely an MLM in disguise. The more a platform focuses on growing its user base instead of its product, the shadier it gets.
4. Check for Transparency
Can you see who runs it? Are the founders real with a digital footprint? Is the company registered and regulated in your country? If it’s all hidden behind a Telegram group or anonymous website, steer clear.
5. Use Trusted Platforms
Stick with regulated exchanges and licensed investment services. If you’re unsure where to begin, platforms like Prestmit can offer you security with real customer support.

Conclusion
If something promises fast crypto riches with little effort, chances are someone is getting rich; it just won’t be you.
Scammers depend on urgency, hype, and the hope that you won’t ask too many questions. But asking questions is actually what protects you.
Stay curious and cautious, and let knowledge guide your crypto journey instead of hype. A little caution can save you a lot of Bitcoin.
