Scammers in crypto are really something. I’ve looked into the history of this sector and honestly, the most devastating rug pulls tell incredible stories of millions (or even billions) evaporated in a few days or months.

Take OneCoin, for example. Between 2014 and 2017, Ruja Ignatova, nicknamed the "Cryptoqueen," sold the dream of the next Bitcoin. Except there was no blockchain behind it. It was just a classic Ponzi scheme that scammed millions of people out of over $4 billion. She disappeared in 2017 and is still at the top of the FBI’s wanted list. I even got caught up in that one back then.

And then there was Squid Game Token in 2021. While everyone was watching the Netflix series, anonymous developers launched SQUID, promising a play-to-earn game. The token skyrocketed from a few cents to $2,856 in just a few days. Then boom, classic rug pull—liquidity drained, price to zero. $3.38 million gone like that.

AnubisDAO was even more brutal. $60 million lost in less than 24 hours. People invested heavily in this fork of OlympusDAO, and bam, all funds drained overnight. It’s probably the fastest rug pull we’ve ever seen.

Thodex in Turkey was different but just as catastrophic. The platform stopped withdrawals in April 2021, and CEO Faruk Fatih Özer ran off with $2 billion. He was later arrested in Albania and sentenced to 11,196 years in prison. Yes, you read that right.

SafeMoon was everywhere in 2021, marketed as a "safe" investment with automatic staking. Except the devs secretly controlled the liquidity and siphoned funds quietly. In 2023, CEO John Karony and others were arrested for fraud. It was a slow rug pull.

BitConnect is the classic of classics. From 2016 to 2018, they promised guaranteed daily profits with an AI trading bot. Pure Ponzi scheme. When regulators shut down the platform in 2018, investors lost over $2.4 billion. BitConnect became the very symbol of crypto fraud.

And then there’s Terra in 2022. Not really a traditional rug pull, but a $40 billion disaster. Do Kwon built an entire ecosystem around an algorithmic stablecoin supposed to stay at $1. When UST de-pegged, everything collapsed. LUNA, USTC, everything. Do Kwon fled, was arrested in Montenegro, and faces lawsuits everywhere.

The lesson? These rug pulls remind us that the decentralization and financial freedom offered by crypto can also become weapons. Caution remains your best defense. Always check fundamentals, teams, and tokenomics before investing.
