Vitalik: Many people lose a lot of cryptocurrencies because they are lost, not stolen

Vitalik Buterin, co-founder of Ethereum, warned that many people have lost a large amount of cryptocurrency not because it was stolen, but because it was lost. Software bugs, forgetting passwords, losing devices, paper wallets burned in the Los Angeles fire, failure to backup data when upgrading devices... all of these situations can lead to losses. Because there is no attacker to blame, victims do not feel a strong need to talk about it.
