downloading bitcoin blockchain and forks

I'm looking to grab just the part of the blockchain that has my transactions. Is that the right approach? Is this what we refer to as a fork? That's what I'm aiming for. Can I do it? If so, how do I go about it? I just want to get the blockchain moving! Also, should I back up my old wallet.dat, or is a dumps.txt good enough (besides the dump files, but correct me if I'm off)? Thanks! Or, you know, does my issue make sense?

or just tell me the name of output debug.log of where is my bitcoins... no speak english or very bad

You don't  need to download the entiry block chain to access to your wallet, there are some light software to do that, you only need to your private key or seed and a lot of common sense. Please try to learn what are you doing before to lose your coins. Please read: Chapter 4. Keys, Addresses, Wallets

1. What do you know ? 2. It's an HD wallet, but encrypt, I have a, a dump.txt of this... before encryption You know... ? can you help me ? do we need to redownload the blockchain? or do you have better technique? I listen to all the suggestions for ideas on Bitcoin-Qt? My first question, : here, Nothing Else ! 3. the question could have been: they transaction and bitcoins, I don’t see them! I don't understand why but I have already received help and it worked, AND I don't have the technical knowledge "commands and logic outputs" and the time to train on github, even if I like this site... "it is very technical"! afterwards if you want an idea of the price I give to solve this problem or help me a lot and move forward on this AND but I don't have the knowledge of DEBUG.LOG to understand everything that's happening! technical knowledge and knowledge of debug.log outputs, that's it! and yes someone has already helped me, and I saw a few bitcoins, that’s really nice! that I put away but now I want to sell part of it, so help, otherwise bye BYE Send a Text Message on bitcointalk, too, I'll respond!

If you have a dump.txt file it should contain private keys that you can import to other wallets. I suggest Electrum you can download it from electrum.org and then learn how to verify the authenticity of this wallet. To verify Electrum you can follow the guide below. - https://bitcointalk.org/index.php?topic=5240594.0 After you installed import the private keys from dump.txt to Electrum. You can follow this guide below - https://bitcoinelectrum.com/importing-your-private-keys-into-electrum/

The problem, I tested! electrum is not for me I must arrive at the following result: AddToWallet imperative!

Sorry for telling you the obvious, but we can't understand much from the text. - Do you want to download the blockchain? If yes, then just spin up a Bitcoin client like Bitcoin Core and let it finish syncing. Import wallets in the process, if you have any. - Do you have a txt file with the private keys? Good, then you can import them in a light client and spend your coins there. - Do you have debug.log in the application directory? That can definitely help us understand your problems with Bitcoin Core, if any.

Okay ok, but what proves to me that you know what you are saying or that you are a professional in the field? the debug.log file is very personal! you know.. so i need proof that you know or you think you know what the mistake might be, or you identify the most plausible problems, okay? Afterwards I can output whatever information you want from the file debug.log okay?  thank you !!

I have these two debug.log outputs, "[net] Saw new cmpctblock header hash" "(slow variant inspecting all blocks)" related to my problem? Is that why I can't see my transactions? what is it? I don't undersatand!* thanks

I want to help you but honestly, it's hard to understand what exactly do you need. I think better to use translator translate.google.com and paste the result here. Or go to the local section from the link below and make a thread there using your native language. - https://bitcointalk.org/index.php#5

This error seems to be related to adding a transaction to the mempool. Check your software is working correctly. Making sure your private key is stored/backed up you can try uninstalling and installing Bitcoin Core again. Likely Electrum will be simpler for you to use.

By downloading a Bitcoin blockchain, I mean syncing your wallet with Bitcoin blockchain, you don't make any Bitcoin fork. If you want to fork a Proof of Work coin, you must have miners to do mining on that shorter chain. If no miner, no hashrate, that shorter or shortest chain will be a dead one. Many scam forks die with time. How many Bitcoin forks are there?
