There is a reason why people call bitcoin “Gold 2.0,” which has become the target of hackers worldwide with one purpose – to steal bitcoin for profit. Bitcoin holds many properties which makes it valuable, with the global market capitalization growing to a current value of $8 billion USD.
Across the world there are over 170 bitcoin exchanges, with new exchanges popping up constantly. For exchangers, the business model is clear. Making money from exchanging fiat-to-bitcoin and bitcoin-to-fiat is there, the demand has risen every year as bitcoin grows and becomes more popular.
With the price of bitcoin being high enough to raise the stakes, the wolves have exited their dens of information hacks which they sell on the dark web, to just going straight to the gift horse and stealing bitcoin directly from exchanges.
To be completely clear, bitcoin itself, the protocol, has never been hacked. When speaking of “bitcoin hacks” the reference is about bitcoin exchanges (and sometimes wallets too!), that have been hacked. Exchanges and wallets are third-party platforms built on top of the bitcoin protocol. Picture your bank, which stores dollars. If the bank is hacked, you don’t say the dollar has been “hacked,” you say the bank which stored the dollar has been hacked. It’s the same premise with bitcoin exchanges.
Hacked exchanges this year
This is a list of bitcoin exchanges that have been hacked so far this year up to now. Hacks could be anything from platform-wide hacks where multiple accounts are hacked, or one person being hacked on the exchange due to platform-targeting, either due to an exploit or poor security practice either on the exchange’s side and/or the user’s side.
