This has nothing to do with bitcoin decentralization.
In brief, bitcoin is decentralized because there is no need to a third party for making a transaction and there are thousands of nodes distributed around the world that help the network.

I just made a search to see what exactly Samsung is going to do.
If the news is real, as you mentioned in your topic, they will launch a cryptocurrency exchange. But I couldn't find any news about allowing people to buy their products with bitcoin. So they don't seem to have any plan to accept bitcoin as a payment method.

You should consider the big difference between golden ticket price and weekly lottery ticket price as well.
Each golden ticket costs 25000 satoshi while each weekly lottery tickets costs only 1 satoshi.

In the last round of lambo lottery, you could have around 0.000087% chance to win 4.910 BTC with paying 25,000 satoshi.
In the last round of weekly lottery, you could have around 0.013% chance to win 0.128 BTC with paying the same amount.

The prize in the last round of lambo lottery was 38 times bigger than the main prize of the last round of the weekly lottery. But If I had put the same amount of money in each of them, my chance to win the main prize of weekly lottery was 162 times bigger than winning the lambo.

This means that participating in the weekly lottery is more reasonable than lambo lottery.
Note that I only considered the main prize of the weekly lottery. Apparently, the chance to be among winners in the weekly lottery is even bigger than what calculated above.

Your suggestion will not work. OP has been banned due to plagiarism and it's no longer possible for him/her to improve the posts quality.
This has already been mentioned in the previous posts made in this thread.  

Edit:
I just reported the topic to moderators and asked them to lock it.

OP is now banned and is no longer able to post in the forum.
It seems that OP understood that he/she needs merit to rank up and tried to earn the first merit with copy-pasting the post made by Gamsa01 above in another thread.

I think The Cryptovator has answered your first question in the topic shared by tranthidung well.

Assume that you have a 100 dollar bill and you want buy something which is worth 50 dollars.
You give your 100 dollar bill to the seller and get a 50 dollar bill. Bitcoin works in the same way. If you have an UTXO worth 0.1 BTC and want to pay someone 0.05 BTC, you make a transaction with your 0.1 BTC. Your transaction will have two outputs. The one will go to the recipient and the remaning amount which is called change is sent back to you.

Now let's go to your second question.
Assume that you want to have 0.1 BTC and wants to pay someone 0.6 BTC. Your transaction will have two outputs. One of them will be 0.6 BTC which goes to the recipient and the change will be 0.4 BTC minus transaction fee.
If the change address is same as the sending address, everyone can know which of outputs is the change and which one is owned by the recipient.  In this way, you may hurt your privacy.
With using a different address as your change address and choosing the outputs amounts in the way no one can know which of them is the change, you can improve your privacy

To add to OP:
The other criteria that can be used for identifying the change address and the recipient's address is the script type used for the addresses.
For example, if you make a transaction from a segwit address to a legacy address and the change is sent to a segwit address, the legacy output probably belongs to the recipient and the segwit output is probably the change.

This website is safe, if it's used offline.
In your first post, you said that the website generates funded addresses.
The tool in question is open-source and it's guaranteed that the keys are generated 100% random. So, it's impossible that it generates an address that has been already used.

I don't know what you mean by account.
There are around 2²⁵⁶ valid  bitcoin private keys. So, if a private key has been generated randomly, it's very very unlikely that it has been generated before.
If there's a website which generate private keys that have been generated before, it means that it doesn't generate the private keys randomly and should be never used.

You should never use a private key you don't know how it has been generated.
You should never use a private key generated online.

If you generate a private key randomly, it's impossible that it has been generated by someone else before.
So, you can't have a private key which has been generated randomly and its associated address has been already funded.

A good alternative is the website created by the forum user examplens, preev.net.
Click here to see the post made by examplens in another thread introducing the website.

This isn't true. The more tickets, the bigger prize pool.
So, with giving users free lottery tickets, they increase the value of prizes and it's not that they don't pay anything for free lottery tickets.

I don't know what specifically you are talking about. But what's the problem if you make a post and some people don't agree with you?
Here is a forum where people can post their ideas about different things freely and without any censorship. It's completely normal that people have different ideas about different topics.

The evidence provided by khaled0111 in the other topic was strong enough and everything is clear now.
You are surely the one who scammed 170 dollar worth of bitcoin from alterra57.

Someone who claims to be that innocent third party has created a topic in "Scam Accusations" board against OP.
$500 exchange scam

The scammer probably abused the RBF feature.
If a transaction has been flagged as RBF, (as long as it is unconfirmed) it can be replaced by a new transaction spending a same input and having a higher fee rate and higher absolute fee.

In your case, the fee rate used for the original transaction was 1 sat/vbyte and it was replaced with a new transaction using the fee rate of 3 sat/vbyte.
In the replacement transaction, the scammer sent the fund to his/her own address.

The 21 million is the total supply of bitcoin and not all of them have been generated yet.
Till now, around 19.1 million bitcoins have been generated.


Although that's possible, you are right. There is no proof of that.

This doesn't mean trustwallet is secure. Everything can happen in the future.


There's still the probability that they track your transactions even if you use their non-custodial wallet.
They can link your transactions and your addresses with your IP address.

Electrum is surely a good choice, but I wouldn't recommend trustwallet. Trustwallet gives you access to your private keys. But since it's close-source, there is no guarantee that you are the only one who has access to the keys.
