Monero won't help if you told people you have a lot of Monero and so you'd get targeted. Even public Monero figures like Doug Thurman of Monero Talk can claim they have only a little Monero because they actually use it, not HODL it (whether true or not). And having an open block chain coin doesn't mean you will get caught...the thief could you just use a DEX or atomic swap to avoid KYC. What would help is good OP-sec practices like never revealing how much you have and always having at least one decoy account with only a little XMR....if you get threatened, give that account up.
Good advice. Did not read the article, assumed the perps transacted with victim and saw they had much coin then followed them home. I guess if they just knew victims were rich and wanted to rob them then no coin can prevent that.
