This is the only flaw on the crypto, the lack of protection for the coin holders, ppl said too bad, this can happen to anyone, I think the developers should work on a way to prevent this actions, Sorry for you lost.
This is not a problem with crypto. Physical currency has the same problem. Banks were created to help people store their physical currency safely. It's simple a problem with the state of bitcoin infrastructure. Soon there will be "bitcoin banks" that will store your bitcoin for you and guarantee safe keeping. They will have take the burden of confirming your identity before allowing the bitcoins to be removed, and will be liable for all unauthorized withdrawals. It's coming, the market will demand it for full adoption.
