This section documents crypto services that are no longer operational — exchanges, wallets, platforms, and other services that have shut down, been hacked, collapsed, or simply disappeared. Whether they went out of business due to insolvency, regulatory pressure, exit scams, or security breaches, each entry serves as a reference point and a warning for the crypto community. Knowing which services are out of business helps users avoid sending funds to defunct platforms and understand the risks of the industry.
The crypto industry moves fast, and not every service survives. Platforms that were once active and widely used can go out of business for a range of reasons — from mismanagement and legal issues to hacks, fraud, and market downturns. This category preserves a record of those services so that users who encounter them in old forum posts, referral links, or search results know not to trust or send funds to them. Each entry includes background on what the service was, when and how it shut down, and any relevant context surrounding its closure. Maintaining an up-to-date list of crypto services that are out of business is an important part of consumer protection — and a reminder that due diligence is essential before trusting any platform with your funds.
