Biggest Crypto Hacks and Scams of All Time (And What We Can Learn from Them)

Habang dumadami ang mga kumikita sa crypto, dumadami rin ang scams at hacks. Eto ang ilan sa pinakamalaking incidents sa crypto history — at ang mga leksyon na pwede nating matutunan.

1. Mt. Gox Hack (2014)

Ninakaw: Over 850,000 BTC (~$450 million at that time)
Dating pinaka-laking Bitcoin exchange, ang Mt. Gox ay na-hack at tuluyang nagsara. Hanggang ngayon, marami pa ring victims na di pa fully nababayaran.

Lesson:

• Huwag itago lahat ng crypto mo sa exchange

• Always transfer to your own wallet

• Not your keys, not your crypto.

2. BitConnect (2016–2018)

Ponzi Scheme disguised as an “investment platform”
Nag-offer ng guaranteed high returns. Kalaunan, bumagsak ang coin at nawalan ng halaga. Estimated loss: $3.5 billion globally

Lesson:

• Pag may nag-offer ng guaranteed profit — red flag ‘yan

• Do your own research (DYOR)

• Stay away from hype-based investments

3. Axie Infinity Hack (Ronin Bridge, 2022)

Ninakaw: $625 million (ETH + USDC)
Isa sa pinaka-malaking hacks sa Web3 gaming. Na-compromise ang validator nodes ng Ronin blockchain.

Lesson:

• Even big projects can be vulnerable

• Be careful with connected wallets

• Wag mag-all in sa isang crypto game or ecosystem

4. FTX Collapse (2022)

Estimated Loss: $8–10 billion
FTX was one of the top crypto exchanges. Pero nalaman na ginagamit nila ang pera ng users sa ibang investments via sister company Alameda Research.

Lesson:

• Even regulated-looking companies can fail

• Wag mag-iwan ng lahat ng crypto sa exchange

• Always check transparency and credibility ng platform

5. OneCoin Scam (2014–2017)

Ponzi Scheme na umaabot sa $4 billion loss
Pinamunuan ni Ruja Ignatova aka “Crypto Queen,” na ngayon ay missing at wanted ng FBI. Niloko ang libo-libong investors worldwide — kasama na ang maraming Pinoy.

Lesson:

• Be cautious with new coins with no real blockchain

• No wallet? No real crypto? Scam ‘yan.

Other Notable Mentions:

• Terra Luna Crash (2022) – over $40B wiped out

• PlusToken Scam (2019) – $2B Ponzi mostly in Asia

• Poly Network Hack (2021) – $600M stolen (then returned)

Conclusion:

Hindi lahat ng kumikislap ay gold — at hindi lahat ng “crypto projects” ay legit.
Ang pinaka-importante sa lahat: Aral muna bago invest.
Wag magpapadala sa hype, at siguraduhin mong secure ang crypto mo.
