Hacker stole my funds from blockchain
I think you should not blame Blockchain.com. They can not provide security as offline wallets. It is possible to use 2FA as far as I know and this is huge mistake you made. Anyway this is a sign of being more careful in the future. You should consider this as a gain not as a loss. Loss could have been bigger.
Another learn to experience thing mate,this will serve as warning to be always careful in every sites we Are visiting because this can be used by hackers to enter you system.sorry for the loss but thats the waybit used to be since this is the most common ways on victimizing cryptonians.
