Just had a major theft earlier this week of $28 million I believe.
And the whole point of bitcoin is that it is secure.
Was. Was secure.
Bitcoin is secure. Exchanges are not secure, just like any other website. People can easily hold and transact bitcoin relatively securely, or hold them completely securely in cold storage. But if people are trying to cash in, or speculate by trading in and out of CC at an exchange, then they are taking a risk, mainly because they legally own nothing in that case.
The thefts of bitcoin and other crypto have occurred due to either exchange hacks (bad website security, not a flaw of bitcoin or other crypto per se) or successful phishing attacks (people voluntarily, but inappropriately, disclosing private keys to others).
