Not quite true.
Take a look at the topic created by ThomasV in November, 2011.
In that time, electrum was using a 12 word seed. That seed was created using a different algorithm from a word list containing 1626 words.

Take note that you don't have to make a request before receiving fund.
You can go to "Addresses" tab and pick any of addresses you see there. All of those addresses are yours and can be used for receiving bitcoin.

If you don't see "Addresses" tab, click on "View" at top of the window and select "Show addresses".

No.

One type of wallets people were using that time was paper wallet. It was a combination of an address an a private key written on a paper.
The other wallet I know people could use that time was bitcoin core.


If I'm not wrong, in the very old versions of electrum, there was a seed phrase which was created using a different algorithm and a different word list.

You can't access it.
The website is down for everyone.


It has been registered 43 days ago and it's probably a scam.



I haven't ever used this website, but there are so many negative reviews on trustpilot.

The website you are referring to is down now and I don't know what they are offering. But whatever they do, I wouldn't trust them. Their domain has been registered only 39 days ago.
 

Seems that there's a problem with the search engine too.
I get an error saying "Something went wrong..." when I try to search for posts or addresses.

The forum doesn't have such a feature. He will get a notification only if he has subscribed to one of notification bots.


Stake has a thread in the forum. (Click here.)
Post your issue there. You may get a better respond.

They should know that yolodice has been closed and you are not able to give then such them details. If they don't know that, tell them that Yolodice has been closed.

Have you ever made any deposit from an address you have full control over?
Have you ever made any withdrawal to an address you have full control over?
If so, tell them you can sign a message from that address. They may accept it as an evidence. (Before that make sure that you can sign message.)

Wallets can be categorized into centralized and decentralized as well.
When you use bitcoin core, you are using a decentralized wallet, because you don't rely on any third party.
When you use a wallet like trustwallet, you are connected to their server and you need to receive data from them. Also, you can't make any transaction inside trustwallet, if they don't want to broadcast your transaction for any reason. This is why trustwallet is centralized wallet.

I also feel that you are confusing decentralization with being non-custodial.  
If you want a secure wallet, it should be non-custodial, decentralized and open-source.

As mentioned above, being non-custodial isn't enough.
For example, in trustwallet, you have full control over your keys. But since it's close-source, there is no way to know if you are the only one who has access to the keys and since it's centralized, you have to connect to their server. This can hurt your privacy.

Another example is mycelium.
In Mycelium, you have full control over your keys and since it's open source and its code has been reviewed by many people, you can be sure that you are the only one who has access to the keys. But there's still a problem with Mycelium. In mycelium, you have to connect to their server.

If you want your wallet to be non-custodial, decentralized and open-source, you can use bitcoin core or use electrum and run your own server.
If you want 100% security, you must create your non-custodial, decentralized and open-source wallet on a air-gapped device and your keys should never connect to the internet.

First of all note that since bitcoin was created, we only had a few upgrades like segwit and taproot to make some improvements. Bitcoin is still bitcoin and will remain bitcoin.
Secondly, it's not that easy to propose an idea and get it approved. The proposal should be supported by vast majority of miners.


In the case by changing fee mechanism, you mean taproot upgrade, note that however taproot makes some transactions cheaper, that wasn't why taproot was proposed. The main purpose of taproot is to improve the privacy.
Also note that maximum supply of bitcoin will never change. To change the maximum supply, we need a hard fork and if that happens, the new coin will be no longer bitcoin.


Every proposal is reviewed by many people and it's very unlikely that an approved proposal causes a bug which ruin bitcoin.

Bitcoin.com wallet assign an ID to every wallet you create and that's completely different from addresses.

To OP:
Maybe, you have multiple wallets on your desktop wallet and you are importing the seed phrase of another wallet.

According to dPlay's terms and conditions, unlike freebitco, there are some restricted countries and it's possible that they ask users to go for KYC. This is why I said that their terms and conditions should be read before registration on dPlay.

If you want to gamble with your fun tokens, you can use dPlay. Connect your freebitco account with dplay casino, so you can use your FUN tokens balance at dPlay.
(Don't forget to read their terms & conditions, if you decided to use dPlay.)

One way is to continue to change the server until one of them sends you the required data.Of course, I doubt any of them do so, but you may want to try you luck.
I don't know if there's any other secure SPV wallet which is helpful to you. Wait, somone may suggest you an alternative to electrum.

The last effort is to run your own electrum server or download the full blockchain and use bitcoin core.

In the case Bttzed03 uses the latest version of windows (Windows 11), internet explorer browser isn't installed by default. In windows 11, microsoft edge has replaced internet explorer.

You imported private key of one of addresses, not private key of one of wallets.
Anyways, that address has probably a big transaction history and servers do not load them due to protecting themselves from attacks.

To test this, I just pressed logout button and it worked well. The problem should be from your side.
Try a hard refresh with Ctrl+F5 or Ctrl+Shift+R and see if it solves the problem.

I feel you have misunderstood OP's problem.
What matters is that whether the deleted file has been overwritten or not and we should hope that OP has shut down the computer and hasn't used it anymore.
Also, according to OP, the text file was deleted more than two weeks ago. It's very unlikely that OP hasn't shut down the computer in these two weeks.

Is there any chance you can find the wallet file?
If you can find the wallet file (and know the password if it's encrypted), you can access your fund without knowing the seed phrase.

If you have deleted the wallet file, I recommend you to follow nc50lc's suggestions for electrum data directory as well. You may be able to restore the wallet file.
