Sorry, it’s gone. Here are some points to take away
Never put all your coins in one single wallet, split it out and stake with different validators Never use your main wallets for any transactions. Always delete or burn all unwanted NFTs without clicking on any. Always use whitelist addresses on your main wallet. Always create a dummy wallet for your transactions.
That’s how you get hacked. If you have a transaction account, use it for that. Do you use your saving and investment bank account for day to day transactions?
