I'm heartbrokren and frustrated not knowing what happend , I was always prepared to lose crypto even I I fully believed in it but not like this. I'm usually the guy that tells others to be paranoid about security.
I get the feeling you're a bit muddled on how Bitcoin wallets actually work. You're mixing up terms and saying things that don't make much sense. All wallets nowadays generate multiple public addresses spawned from one original seed and this covers change addresses too. So there's no master address or single address that represents your entire wallet. Unless you imported the wallet using a private key - that wallet would have only one public address (well actually three, depending on the script type, but I won't get into that).
I strongly recommend you ask someone with more expertise for assistance if you dont wanna risk losing your money forever with amateur moves.
yeah well that s why i m here, like i ve said i didnt keep up with wallet updates, i know the principle, i had no idea about generating multiple adresses, i knew my adress, where i received some btc from some people, and i used bt core always to buy somt, since 2022 untill 2024 i didnt buy or do anything.
then this year i bought 4 games or so, when i closed the bt core , amount was right, i always check amount of wallet, because i never trust anything
yesterday i wanted to buy something, because it allowed only crypto, and since i had to resync all bt core wallet, since 2008 would ve took 12 hours , so i installed electrum, once i installed electrum (downloaded from their official site electrum.org), i entered my pass for default adress, and shock and horror i had not even half of my btc (around 0.1 now only 0.039) so i checked blockchair of my adress , main adress i always used terminating in ydo and horror it was only 0.039.
so what should i do now?
install the btcore , newest and use my 2022 wallet ?
try to search for the latest wallet.dat file i used when i made the last transaction?
