When TOPBTC, a crypto exchange that once promised fast trades and low fees vanished overnight, users couldn’t access their funds. No warning. No explanation. Just silence. This isn’t the first time a crypto platform disappeared—EQONEX, a regulated exchange that filed for bankruptcy in 2022, and Metal X, a U.S.-based exchange that shut down in 2021 before reviving as a DEX both followed the same path. These aren’t random failures. They’re symptoms of deeper problems: weak oversight, hidden debt, and a lack of real transparency.
Most exchanges that collapse don’t get hacked—they just run out of money. They promise high yields, attract deposits, then use customer funds to cover losses or fund risky bets. When the market turns, or when withdrawals spike, they can’t pay back users. KyberSwap Elastic, a DeFi platform that lost $56M in an exploit didn’t vanish, but its trust did. Same with Syncswap (Scroll), a DEX with broken token purchases and zero support. These aren’t just technical issues—they’re trust failures. And when users lose trust, the whole system cracks.
The pattern is clear: if an exchange doesn’t publish regular audits, doesn’t use multi-sig wallets for reserves, and doesn’t have a clear legal structure, it’s a gamble. You’re not just trading crypto—you’re betting on the people running it. The GENIUS Act, a new U.S. law requiring stablecoin issuers to hold 1:1 reserves is one step toward fixing this. But until then, the burden is on you. Check if a platform has real liquidity, public proof of reserves, and a track record. Avoid anything that sounds too good to be true. Below, you’ll find real case studies of exchanges that vanished, scams disguised as opportunities, and lessons from users who lost everything. This isn’t theory. It’s survival.
TOPBTC was a defunct crypto exchange that shut down in 2020 with no warning. Its flat fee model and missing deposit info made it unreliable. Today, it serves as a warning: never trust an exchange you can't verify.
