Not all exchanges work is this way.
In blockchain.com trading account which is the topic of discussion here, you can withdraw your fund to any address you want directly without any need to moving the fund to another account or your main wallet.
For example, kucoin is one of the wallets works in the way you described above. In Kucoin, each user has two accounts. One is for trading and the other one is used for deposits and withdrawals.

No. There is no evidence of that and I don't think  they are alternative accounts.
But generally speaking, if I send you 10 merit and tell you "I sent 10 merit to you and now I don't have any smerit. Can you please send me 5 merit?", it would be still merit exchange.


You are right. I also took a look at his history and just sent him 6 merit.

Wouldn't that be like a merit exchange?
BRINIRHA received 11 merit for a post that doesn't deserve to receive merit. This was the first mistake. If BRINIRHA sends 5 merit to Gallar just because he/she has received 11 merit mistakenly, it would be the second mistake.
This is just my opinion and I think the best thing is to forget about what happened.

A 12 word seed phrase is enough.
A 12 word BIP39 seed phrase provides 128 bits of entropy. Since a private key provides the same amount of entropy, with increasing the number of words to more than 12, you don't really increase your security.
Keep your 12 word seed phrase safe and don't worry.

It was only the name that was changed and there isn't any big difference between them. Bitcoin QT was actually rebranded to bitcoin core in that time. Whether a wallet has been created by bitcoin QT or Bitcoin core, it should have created a wallet.dat file.
Please correct me, if I am wrong please.

To OP:
Since you have used your wallet for mining in 2010, you should have a wallet.dat file.

As already mentioned above, try to find a wallet.dat file or your private keys.
Note that if your wallet.dat file is encrypted, you will need the passphrase for decryption as well.  

If a post needs to be deleted, I am pretty sure both LoyceV and TryNinja will delete the post from their website.

LoyceV has already done so. See this post.
TryNinja will do the same if that's required and he receives a request. See this post for more information.

Note that the deposit address they give you isn't owned by you. The address is owned by the exchange and they give it to you, so you can make a deposit. You have no control over that address.
So, when you sell your bitcoin to someone in the exchange, there is no need to make a transaction from your deposit address to someone else deposit address. All deposit addresses are owned by the exchange and they have full control over the funds, whether it's in your deposit address, another user deposit address or their hot wallet.

Blockchain.com trading account works like an exchange and you can trade bitcoin and some other cryptocurrencies there.
In blockhchain.com, there is no funding account or something like that. If you have verified your identity, you should be able to withdraw your fund from your trading account to your main wallet or any address you want directly.

Even if the website isn't compromised, that's like using electrum on an online device and there's still the chance that your computer is compromised.
The safer method (not the safest) is to save the webpage as a file, move it to an air-gapped device and use it there.

The transactions shown in the images you shared have been made from your trading account, not your wallet.
I haven't ever used blockchain.com trading account and I don't really know how it works. I just know that KYC is mandatory in blockchain.com trading account. Have you verified your identity? That may be why they haven't processed your transactions.
Contact blockchain.com support and ask them why these transactions haven't been processed. They have full control over trading accounts.

Many people have already done so. That's very easy. Currently, there are many other cryptocurrencies (called altcoin), but none of them have been able to compete with bitcoin.
None of the altcoins have been able to provide the security and the decentralization bitcoin gives us.
Just go to coinmarketcap.com and see how many coins/tokens have been already created.

According to blockchain, no transaction has been between these addresses.
Given the transactions received and sent by 3EkKxC1kDrJc4MvRqkXXyt7mpiA5UCLoRs, it seems to be owned by a custodial service like an exchange and can't belong to your blockchain wallet.

It's impossible that you have made a transaction from this address using your blockchain wallet.

You can use transaction accelerators like ViaBTC when your transaction is unconfirmed and you want it to be confirmed fast.
The case is different here. The transaction hasn't been broadcast to the network and doesn't exist in the mempool at all.

OP already said that he was using tradingview chart. See this post.
Since Tradingview uses the data extracted from Bitstamp by default and Bitstamp's volume has decreased, he/she thought that bitcoin trading volume has decreased.

The chance of winning the biggest prize (The $15,000 Rolex) is 1 in 2 billions.
The chance of winning the $1500 iphone is 11 in 1 billion.
The chance of winning the $500 Amazon gift card is 3 in 100 million.

You can calculate the winning chance of each of other prizes using the following table easily.

It's impossible that you have a transaction that is still unconfirmed after 5 months.
In these 5 months, the mempool has been emptied many times. Also, as mentioned by BlackHatCoiner, unconfirmed transaction are usually dropped from the mempool of nodes.

What you shared above isn't a valid transaction ID and I guess you are using a custodial service that hasn't broadcast your transaction even after 5 months. What's the service you are using?

If you use the online website, you are right. That's not safe. Even if you enter your seed phrase on iancoleman.io and not a fake website, there's still the chance of getting hacked.
Iancoleman is open source and if you want to use it securely, you should download the source code and run it offline on an air-gapped device.
Take note that any online website and any online wallet (including Coinomi) is unsecure.

I would no longer post in this forum, if I believed that my posts are deleted without being reviewed by a human and they are all deleted by a bot.

You are right. Moderatos don't waste their time on monitoring your activity.
Moderators review your posts if they are reported. It's not that they are always looking at your post history to check if you have made a new post.

Tradingview allow you to change the data source.
Just click on "Bitstamp" to see a list including some other exchanges. I don't know why by default it has been set to Bitstamp. Maybe, it's kind of advertising.




Coingecko is a website for tracking different cryptocurrencies prices.
The price and trading volume reported on coingecko is calculated using the data extracted from different exchanges with weighted average formula.

Iancoleman's domain hasn't been changed and I can access the iancoleman.io without any problem.
It's the first time I've heard of the .ch domain and that's probably a fake website created for scamming purposes.

Edit:
I just searched for "iancoleman" on google.
It shows the .ch domain as an advertisement. It's not the first time I see google is promoting scams.
