hello, i have bitcoin core.
I downloaded my blockchain,
I can open my wallets,
1 Opening hour of 1 wallet,
I don't see anything,
no coins, no transactions,
There must be, it is SURE ...
As per my previous response to your other thread... if you have a fully synced,
non-pruned Bitcoin Core node (ie. it has ~400 Gigs of blockchain data downloaded and stored and is currently up to block# 694088 or higher)... and you load in a wallet.dat and the wallet is rescanned, which it seems to be given that it is taking an hour to open the wallet.dat... and you then see nothing...
Then the wallet is empty!

You're not even seeing any transaction history, so the wallet files appear to be completely unused. It's also possible that the wallet files could be altcoin wallets, although they would still likely contain some sort of transaction history and they'd just show up as "unconfirmed, not in mempool" type transactions in the history list (as they would not be in the Bitcoin blockchain data).
is it possible that the funds are hidden,
incorrectly downloaded, because of modified option?
on my address,
Normally there are parts on it!
The funds cannot be "hidden". Bitcoin is a "public" blockchain. All transactions are visible to everyone. If the wallets contained the private keys to any addresses that were used in a transaction on the blockchain, then they would show up in the transaction history.
Bitcoin Core has plenty of checks to ensure that the downloaded data is valid. That is how blockchains work... each block in the chain builds on the previous one, so any invalid block is easily identified and discarded.
So, if things were incorrectly downloaded, you'd have invalid blocks and you'd either get warnings about it, or Bitcoin Core will ignore then invalid blocks and redownload the correct data.
Again, assuming fully synced, non-pruned node, if you're seeing no transaction history, then the wallets are unused. If you see transaction history, but a zero balance, then the wallet is empty.
