By Common Bitcoin Scams, and How to Spot Them
Bitcoin's cryptography has never been the weak point in a real-world theft. Every well documented case of someone actually losing funds traces back to one of a fairly small set of recognizable scam patterns, most of which have nothing technical about them at all.
The giveaway scam
"Send 1 BTC, get 2 BTC back," often posted from a hacked or impersonated account belonging to a celebrity, company, or public figure. There is no legitimate version of this offer. It relies purely on urgency and the appearance of authority, and the moment funds are sent, they're gone.
Phishing sites and fake wallet apps
Convincing clones of real exchange or wallet websites, or fake mobile apps listed briefly on official app stores, designed purely to capture a seed phrase or private key the moment it's entered. Always verify a URL character by character before entering any credentials, and never enter a seed phrase into a website under any circumstances.
Fake support and "recovery" scams
Someone reaches out, often after you've posted publicly about a crypto problem, offering to help "recover" lost funds or fix a wallet issue, then asks for your seed phrase or a small upfront "gas fee" to release your funds. No legitimate recovery process ever requires your seed phrase, and legitimate help never needs an advance payment to release money that's supposedly already yours.
Romance and "pig butchering" scams
A long-run scam, often starting on a dating app or social media, where a scammer builds a relationship over weeks or months before introducing a "guaranteed" investment opportunity, typically a fake trading platform showing fabricated gains to encourage larger and larger deposits. These scams are named for the practice of "fattening" a victim before the loss. They're patient, well organized, and often run at scale.
Fake investment platforms and cloud mining scams
Sites promising guaranteed or unrealistically high returns, sometimes styled as "cloud mining" services that supposedly mine Bitcoin on your behalf for a fee. Real mining profitability is thin, competitive, and never guaranteed; any offer promising fixed, risk-free returns on Bitcoin is a red flag regardless of how professional the website looks.
Rug pulls
More common in newer tokens than Bitcoin itself, a rug pull is when a project's creators abruptly withdraw all liquidity or funds and disappear, leaving a worthless token behind. The warning signs are usually visible in advance: anonymous teams, no audited code, and outsized promised returns for a brand-new, unproven project.
The pattern underneath all of them
- Urgency: pressure to act immediately, before you have time to verify anything.
- A request for your seed phrase or private key, framed as necessary for "verification," "unlocking," or "recovery."
- Promises of guaranteed or unusually high returns, a claim no legitimate investment can honestly make.
- Contact that you didn't initiate, especially after posting publicly about a crypto issue.

Every scam on this list works by convincing someone to hand over access voluntarily, not by defeating any cryptography.
