Does  "!" always consolidate all the coins to the change address, if coin control isn't used?

Let's say I have two UTXOs.  UTXO_A is worth 0.04 BTC and UTXO_B is worth 0.06 BTC. I have received these two UTXOs in two different addresses.
Now, I want to send 0.05 BTC without using coin control feature. As far as I know, electrum would use the UTXO_B and wouldn't use UTXO_A at all. 0.05 BTC will be sent to the recipient and 0.01 BTC minus transaction fee will be sent to the address specified using "!". So, my coins won't be consolidated. Correct me if I am wrong, please.

From my understanding from the article you shared, only people from United States are allowed to withdraw 2,000 dollar worth of cryptocurrencies without going for verification.
People from other countries have to verify their identity for withdrawing any amount of cryptocurrencies.


It may worth mentioning that the withdrawal limits apply to their exchange and it has nothing to do with their wallet.

Right. With stealing testnet coins, the hacker actually warns about using a fake version of electrum. No hacker would do that.


OP already said that he/she generated the private keys through a brainwallet and used so simple words. See this post.

As I said in my previous post, there is no way to derive a private key from a bitcoin address or a public key. The public key is derived from a private key through a one/way function.
If it was possible to derive the private key from a public key or an address, then everyone could steal all the bitcoins.

Any wallet that is connected to the internet is called hot wallet. So, you are using a hot wallet.
There's always the risk of being hacked in hot wallets and I would never recommend anyone to use a hot wallet especially when it comes to close-source wallet like trustwallet.
Just because you haven't had any problems before doesn't mean trustwallet is secure and you won't have any problem in the future.

I don't really understand what you are trying to achieve.
Why the first 35 characters and why not the first 20 or 40 characters?
What do you have now? What do you want to derive the private key from? Are you trying to convert a private key in hex to WIF format?

Note that if you have a bitcoin address or a public key, there is no way to derive the private key from them.

It has worked.
By sweeping your private keys, you actually made a transaction to your electrum wallet.
Now, your transaction has been broadcast to the network and you should be able to see that on block explorers as well. It will be confirmed sooner or later.
The confirmation time depends on the fee rate you used for your transaction. Whatever fee you paid, it shouldn't take long. Network isn't busy.

You have missed the first 35 characters of your private key and now you want to calculate them? Am I getting you correctly? If so, there is no solution for that.
If you had missed a few characters, you could find them through brute-force method. But there is no way to brute-force a private key with 35 missing characters.

jmlkav6699, Armory doesn't work if you download the blockchain in prune mode. I knew this, but I don't know why I forgot to mention that when replying to your other topic. I am sorry.
If you can't store the full blockhchain, as mentioned by BitMaxz in that topic, the only solution for you is to import your private key(s) into a SPV wallet like electrum.

If pruning was enabled when downloading the blockchain, that's what caused the problem.

I don't have any information about poker and I don't really know how your giveaway will work, but since you are going to pay the winner(s) with bitcoin and not with an altcoin, I don't think there's any problem with your topic.
"Games and round" should be suitable for such a thread.

If your wallet isn't compromised and you are sure that you have downloaded electrum from the official website, maybe it's your device which is compromised.
Can you try creating a new wallet on a different device and check whether the same thing happens or not?

Yes.
If I don't want to see the signatures below the posts, I can easily go to my profile and change the setting, so signatures are not shown.
If you post a signature below your posts and I don't want to see them, I can ignore your posts or report them.
If all the users do the same thing, I can do not nothing. So, the best is to not allow users to add signatures to their posts at all.

Maybe, OP edited that post and added something later.

Take note that the odds aren't determined by the house. Freebitco is using Parimutuel betting system and the odds are determined by the users.
In freebtico, all the money that has been bet on an event by all the users goes to a pool. 5% of that goes to the house and the 95% is shared between the winners.
The odds depend on the total money that has been put on the event, the money that has been put on each of outcomes and the time weight multiplier.

Are you saying that you sold some coins at $40,000 and after that the price dropped to $3000 ? Am I getting you correctly?
If so, I don't remember the price ever dropping from $40,000 to $3,000.
Bitcoin dropped to around 3000 dollars in December 2018 and the ATH was around $19,800 at that time. Bitcoin reached $40,000 in January 2021 and $60,000 in March 2021.

You probably made a typo, but it may worth mentioning that it's neither electron nor electors. The wallet is called Electrum.

Anyways, it's possible that your computer is infected with a malware or you are using a fake version of electrum, however I don't know why a hacker should steal worthless testnet coins.
Where did you download electrum from? Did you download electrum from its official website (electrum.org) or somewhere else?

This is wrong.
Prune nodes validate every block and transaction they receive.


This is not possible.
In this way, the node that wants to validate the transaction doesn't know whether the coin exists or not. The node doesn't know whether the coin has been spent before or not.
For validating the transactions, nodes need the full database of UTXOs.

The question is how you will be able to verify the transactions that will be made in the future. That's one of the main purposes of keeping a copy of blockchain.
For validating the future transactions, you need database of all UTXOs and they can't be derived from transaction hashes you have stored.

If you only store transactions hashes and you don't have database of all UTXOs, it won't be possible to verify the transactions that will be made in the future.
There is no way to derive the transactions details and UTXOs from the transaction hashes and the hashes you store are completely useless.

If you want to store smaller size of data, you can run a prune node. If pruning is enabled, old blocks are removed, so you don't require a big space for storage.
I think in this way you even store a smaller size of data than your proposal. Because, you store nothing from fully-spent transactions.

It's not that it can't be profitable to mine bitcoin in the current bear market.
A few days ago, the total hash power of bitcoin reached its all time high. That wouldn't happen if mining couldn't be profitable.

Whether mining is profitable for you or not highly depends on the price of electricity in your country.
You can use mining profit calculators like whattomine or asicminervalue to see whether it's worth to mine bitcoin for you or not.
