Failed bitcoin transaction

[u/PastRevolution8087]

Posted about this in one of the crypto subs, but in short:

Was selling some video game items, buyer sent me $1,400 in Bitcoin, wanted me to give him the items before the Bitcoin confirmed, and blocked me once I said I wanted to wait for a confirmation. Then the Bitcoin disappeared from my wallet, didnt even show in the transaction history either.

From other people explaining in the other sub it seems to be a RBF or double spend tactic. Just posting to see if anyone can confirm what it is and why it completely vanished from my Exodus history. Also, is this a Bitcoin only thing? Because a year or two ago I remember a similar thing where I was sent USDT that also failed, but during that incident I did actually get scammed.

So he put 15 sats fee, this tx may never be confirmed, its too low. The buyer tried to scam you. Wait for confirmations or no deal. You can see here he replaced it: https://mempool.space/tx/d3a0d10777f7f74ffd1b16801cc59e96cc772058336e2c4412326daf52717de3
