In this unregulated market, i think nothing we can do when our wallet hacked. Cryptocurrency is transparant ledger but we can not know who own the wallet because its anonymous.
indeed, at the moment the crypto market is still free and no one has held it, so there are still many people who still do not have trust so they commit cyber crimes and hack all the data we have including our wallets that they can take too,
therefore we need strong protection.
