Hi all,
I was expecting a transfer of $1000 in btc.. I saw incoming of $1000 in my wallet, then i also saw $100 incoming from the same sender.
20mins later the $1000 vanished and i had only $100 left.. Can someone confirm what exactly happened? Im confused. I thought once a transfer is sent and you see it on incoming it cant be changed or modified?
The OP explained exactly the experience of RBF in his own question. no need to beg him to supply TXID as the vanished $1k version is gone(rejected) so no investivation or new info can be gathered
the 20min wait for the $1k to be left unconfirmed shows an in sufficient fee was paid, thus later the $100 appear with a priority fee(higher) and so at the 20th minute the $100 confirms thus completely making the $1k rejected.
in short yes the sender done a RBF scam on the user and the user should demand the remaining $900 off the sender if the receiver required $1k
as for others warning about not to blindly trust zero confirms. this is true for amounts more then the price of a soft drink. pizza of something small. and especially true for the subnetworks that mess around with unconfirmed 'smart contracts' that dont settle. as they too have many ways to switch around which tx gets confirmed finally later on
