Criminals are getting better at Wrench Attacks.
Some attacks are now worth millions of dollars.
This is why Privacy Coins are so important, and you should never brag about the size of your bags, and never pay for things from a public ledger wallet where people can trace back to see the size of your bags.
i try to use monero for every transaction, and if they dont accept it, i ill use exch.cx to convert it to whatever crypto they do accept and send it out from there bags. May look like i own that or the transaction is coming from an exchange but i really do not own that pool of funds, and maintain my privacy by staying in xmr.
