What? Am I getting this right?
Are you saying that in every difficulty adjustment, the difficulty can increase up to 4 times the previous difficulty and it cannot decrease to less than 1/4 of the previous difficulty?
It's the first time I've heard this.
I just made a search and couldn't find any information about this.

Edit:
Can anyone confirm if there's such a rule?

If you use the GUI for creating a 2FA wallet, electrum generates a multi-signature wallet in which the addresses start with bc1q, not with 3 and that's probably where OP's problem comes from.
In order to create a 2FA wallet in which the addresses start with 3, you have to use console.

make_seed(seed_type="legacy") is not a valid command. For creating a legacy wallet using console, you should use one of the following commands.




make_seed(seed_type="2fa") works. It can be used for creating a non-segwit 2FA (starting with 3) wallet in electrum while the GUI only allows you to create a segwit 2FA wallet.

If blacklisting pools own 95% of the total hashrate, they can simply reject the blocks mined by the 5% non-blacklisting pools too.

Let's say my transaction is rejected by blacklisting pools and it's included by a non-blacklisting pool.
Most probably, the 95% blacklisting pools won't add any block to the chain including my transaction. We will have a hard fork, then? Or maybe even non-blacklisting pools will join the blacklisting pools and will add the new blocks to the longer chain?

Yes,
If you have wallets made with version 4.0.9 and before that, for creating a new wallet in version 4.1.0 and after that, you must unlock an existing wallet. It doesn't matter which one you unlock.
Once you open a wallet, it allows you to create a new wallet. The password of the new wallet will be same as the password of the wallet you unlocked.

I confirm this.
I created wallet A and wallet B with the version 4.0.9 and then updated electrum to 4.1.4. I unlocked wallet A and created wallet C.
There was no change in the password of wallet B.

I changed the password of wallet C using "Change your password for this wallet". Now I have three wallets with three different passwords.


I cleared electrum's data and created two new wallets (with 4.1.4)
I went to "setting" to check if it's possible to change the password of one the wallets without the other one being affected.

There was no "Change your password for this wallet". Instead, I have "Change your password" option.

Conclusion:
If all wallets have been created with the new version (4.1.0 and after that), there is no way to have different passwords for different wallets.
If you have already wallets with different passwords, even wallets created with 4.1.0 and after that can have unique passwords. (To do so, you must create a new wallet with a password same as one of existing wallets and then go to setting and change its password).

Let's say I create wallets A and B with 4.0.9. I update electrum to 4.1.4 and create wallets C and D. It's possible to have four different passwords for these four wallets.

I don't think RapTarX meant those numbers. Posts IDs are unique numbers allocated to forum posts. If they change, then all the links to the posts should change too.
For example, the post ID for the post number 2 is 57307364.

The only thing that comes to my mind is ask Charles-Tim to edit his post and add the content you want.
Since the post number 4 is yours, the other solution is ask Charles-Tim to delete his post.

The command is correct and it should work. Even if the command is not correct, it should return an error.
Did you press "Enter" button on your keyboard after pasting the command in console?

I don't get what you mean. Do you mean you want to create a 2FA wallet in electrum?

As stated by LoyceV, the problem is probably with the address type.

If you want to withdraw bitcoin from that service to electrum, you must create a legacy wallet.
Since electrum version 4.1.0 and after that doesn't allow you to generate a legacy wallet in the GUI, you have to use console.

Go to console tab and paste the following code to get a legacy seed phrase.
(If the "console" tab is not available, click on "View" at top of the window and select "Show console".)


After that create a new wallet. Select "Standard wallet" and then "I already have a seed". Paste the legacy seed phrase.

No, that's not the reason.
As long as your post size is below the 64000 byte limit, you can post any number of images you want.

I just visited one of the links you used for sharing an image to see what's the problem
The problem is that you have pasted a wrong code in your post. You must use the BBCode.

You answered yourself.
The reason is that you can't withdraw your dogecoin from HITBTC. This means that you aren't actually buy doge in HITBTC. Instead you are buying something that comes out of the thin air and has no value.
If they don't open the withdrawal, the price will drop to zero gradually.

Two groups of people are now buying the fake DOGE on ViaBTC.
The first group buy DOGE once they see the low price without thinking about the reason.
The second group are actually gambling. They buy DOGE and hope that hitBTC open the withdrawal one day.

It's not the first time I hear of shady activities from HITBTC and I would never put a penny on such a shady exchange.

By the way, I think "Service Discussion (Altcoins)" is more suitable for this topic.

Just an assumption:
You opened an existing wallet in which all addresses start with 1.
You clicked on "File" and then "New/restore" and created a new segwit wallet.
Now you have two wallets (the one you just created and the one that already existed) open.
For checking the addresses, you looked at the wrong wallet.

Thanks for the information. I haven't noticed this. So, it's different from how the desktop version works.
As stated by Charles-Tim, I also believe that it would be better to allow users to have different passwords for different wallets.

Assume that I have written my password on a paper. I don't have access to the paper now and I want to create a new wallet. I have to delete all existing wallets for creating the new wallet.


Thanks for the testing. I was going to install an old version to see how it works.
So, I think there is no need to open a github issue anymore.

I have created a wallet on android version of electrum and now I want to create a new wallet.
When I open the application, it only allows me to open the existing wallet and there is no option for creating a new wallet.
For creating a new wallet, I have to open the existing wallet first. The following image is the screen displayed after opening the application.



If I tap on "Cancel" button, I exit the application.
If I tap on the "wallets" icon above the screen, It takes me to a new screen where the "New" button is grayed out. (Shown in the image below)




Therefore, if you have forgotten the password of your existing wallet, there is no way to create a new wallet unless you remove electrum's data from your device.

Is this a bug? I doubt it's how it should be.
I am using the latest version of electrum (4.1.4)

In Electrum versions 4.1.0 and after that, you can't generate a legacy wallet using the GUI.
Of course, you can still import a legacy wallet (whether a BIP39 seed or a electrum's seed) into electrum. You can also generate a legacy seed phrase using console.

As already stated by ranochigo, it's impossible that your addresses change.
When it comes to eletrum's seed phrase, there is no way to create a segwit wallet from a seed generated for a legacy wallet at all.

You are right. OP doesn't need the secret key if he/she has the seed phrase. The seed phrase can generate two out of the three master private keys and is enough for spending the fund from the 2 of 3 multi-signature wallet.  

In that post, I considered the case OP doesn't have the seed phrase too.
I said that OP needs to have the {seed phrase} or {the wallet file plus the secret key}.
Perhaps, my wording wasn't clear enough.

It seems that there's an extra word in your signature. You have probably copied the extra word from your bounty thread by mistake.



Go to your profile and then "Forum Profile Information". Delete the the word "code:" from the first line of your signature.
Your signature code should start with [center ] and that's should be in the first line.

As stated by dkbit98, bitcoin is a proof of work cryptocurrency and cannot be staked.

I just made a search to figure out how their staking system works and couldn't find anything about earning bitcoin with their application. From the information I could find, they only offer staking an altcoin issued by themselves. They won't give you any bitcoin.

Just a small correction:
The minimum fee you have to pay for a transaction is 1 sat/vbyte not 1 sat/byte.
A transaction with segwit input(s) can be broadcast even with less than 1 sat/byte.

---

To OP:
As every block has a capacity of 1 vMB and miners can't include any number of transactions in a block, they prioritize transactions based on their fee rate per vbyte to maximize their profit.
So, the higher fee rate your transaction has, the more quickly it will be confirmed.

The fee rate you need to set for a transaction depends on how fast your transaction want to be confirmed and the network status.

Also note that you can pay a lower fee if you use segwit addresses as inputs.
There are two kinds of segwit addresses.
1. Native segwit: addresses that start with bc1
2. Nested segwit: addresses that start with 3.

The current minimum fee rate for using their free accelerator is much higher than 1 sat/vbyte. For free acceleration, the free rate must be at least 10 sat/byte. For accelerating any transaction paying lower than 10 sat/byte, you have to use their paid service.

---

To OP:
As already stated by NeuroticFish, your transaction fee rate is probably less than 10 sat/byte and you can't use their free service.
Even if you have made the CPFP transaction with more than 10 sat/byte, you won't be able to use their free service. They don't accelerate transactions that have unconfirmed parents freely.
