According to @0xfoobar on Twitter, crypto traders are advised to keep some cash and valuables at their residence but never store cold wallets at home. This operational security measure is designed to deter home invaders from resorting to violence if they cannot access digital assets, while providing a decoy that satisfies immediate criminal intent. Proper cold wallet storage offsite minimizes the risk of forced compromise and potential loss of cryptocurrency holdings. Traders should regularly review their physical and digital security protocols to safeguard assets, as recommended by @0xfoobar (Source: Twitter/@0xfoobar).
