This is one of very few reasons why having centralised banks is going to be necessary. Whether the pros of having banks outweigh the cons decentralised currencies, is yet to be determined. Personally, I still don't believe they do.<p>Anyway, the usual bank transaction care should still apply, especially _because_ there is no central authority to reverse charges. Normally when I send money to anyone, I check it first by sending a small amount, then I get confirmation that it's received, then I'll send the rest.<p>I don't know if such a precaution would have made sense in this scenario (as I don't know enough about LINK or smart contracts for that matter), but it's something that I take especially serious when transacting large amounts in crypto currencies.
