You can't find a wallet being able to receive 1 satoshi. Nodes don't allow that.

The minimum amount of bitcoin you can send is 547 satoshi.
Any transaction including outputs worth less than 547 satoshi is considered as dust and is rejected by nodes.
The purpose of this limitation is to prevent attackers from spamming the network.

Are you sure that you haven't already claimed that free spin?

The "This free spin has expired..." message is displayed in two cases.
    1. You click on the banner more than 48 hours after you receive the email.
    2. You have already claimed the free spin.

3MxaTKLroUitGF8yftF5VQTEsdtm26xb3Z is your change address. This means that the address is used for receiving the remaining balance of selected UTXOs.

Let's say you have received 1 BTC in a transaction and you want to send 0.4 BTC to address A.
You can't send the 0.4 BTC without touching the other 0.6 BTC. Therefore, your wallet sends 0.4 BTC to address A and sends 0.6 BTC (- fee) to your change address.
Note that you own 3MxaTKLroUitGF8yftF5VQTEsdtm26xb3Z as well.

You can use jochen-hoenicke website to check the fees on Litecoin blockchain.
As shown in the past week graph, total size of unconfirmed transactions paying 0.00000001 LTC /byte has always been less than 1 MB.

Yes, using a non-custodial wallet, you can pay only 0.00000001 LTC/byte as transaction fee and get confirmation in the next block
A transaction with 1 input and 2 outputs is only 217 bytes. So, it's possible to get a very fast confirmation with paying only 0.00000217 LTC = 0.0005 dollar.  
The transaction fee can be even lower if you use segwit addresses (addresses starting with M).

The general rule is that, for implementing CPFP, you need to have control over one of outputs of the unconfirmed transaction.
If you you send the entire balance of inputs to another person, you can't implement CPFP.
If you don't send the entire balance, your transaction will include a change address and you will be able to implement CPFP.

Let's say you send bitcoin from address A to address B. (You have control over address A and have no control over address B)
If you haven't sent the total balance, your transaction will be as follows.

Address A -----> Address B
                         Address C

Where address C is your change address and contains the remaining balance of address A.

CPPF can be implemented by owner of address B and owner of address C (you).

Both tokens you were trying to withdraw (BAT and USDT) are ERC20 tokens. This means that that don't have their own blockchain and are running on ethereum blockchain.
Sending an ERC20 token is even more expensive than sending Ethereum. Because the transaction needs to spend more gas due to larger size of data.


I just visited Bilaxy to check networks they support for withdrawing USDT. They support Tron network as well.
For withdrawing USDT on Tron network, you must select "TRC20" option.
The fee they get for withdrawing USDT on Tron network is 2 USDT and the minimum withdrawal amount is 5 USDT.

PSG vs Chelsea?
The last time Chelsea and PSG played against each other was about 5 years ago in 2015-16 champions league.
The last game of Chelsea was against Porto and the last game of PSG was against Bayern. Both games have been ended and prizes have been given to winners.

By disconnecting your internet, you don't really make your wallet more secure.
It's advisable to run electrum on an air-gapped computer. This means that you should use a computer which has always been offline and will never get online.

Assume that there are 100 users in the lottery and each of them has 10 tickets.
User A owns ticket numbers from 1 to 10. User B owns ticket numbers from 11 to 20, and so on. Every week freebitco publish a list in their twitter to let all users know ticket numbers they own.

Let's say the first ticket picked is ticket number 5. The user A wins the first prize. If the second ticket number is between 1 and 10, that's discarded and calculations are done again.

You can click on "This lottery is provably fair" in "lottery" section and read the full explanation.


The user who owns the first winning ticket wins the biggest prize, not 10th prize.

Your chance is 0.006% not 0.006.


That's correct too.

436/2,782,350 = 0.0001567 = 0.01567%

The 0.0001567 must be multiplied by 100 to get the percentage.

The lowest possible fee rate is not 1 sat/byte. That's 1 sat/vbyte.
A transaction including segwit inputs can be broadcast even using less than 1 sat/byte.

As an example, take a look at this transaction. It is paying 0.672 sat/byte.

As there are 10 prizes, your chance to win one of them is

(^{Your tickets} / _{Total tickets} )* 10

(Since no one can win more than one prize, your chance is actually a bit higher, off course)


It's impossible to win more than one prize.

For determining winners, some mathematical calculations are done.
In the case the picked user has won one of previous prizes, calculations are done again.

You have to pay more fee for sending tokens because you have to spend more gas.
The used gas is something like transaction size in bitcoin transactions.
When you send tokens, your transaction includes some extra data and when it comes to transaction size, it's larger than a simple ethereum transaction.

The exact fee you have to pay depends on the token you send.
Since every token has its own contract, the size of data you broadcast to network differs from token to token.

The fee you pay for a transaction depends on gas price as well. The gas price depends on network state and changes over time. That's why you have to pay different amount of fee for a same token in different times.
Note that the gas price doesn't depend on the token you send.

Ethereum transaction fee is calculated as follows.
Fee = gas price * used gas

The 130 Gwei you are referring to is the price of one unit of gas, not the total fee.

In a simple ethereum transaction (I mean a transaction in which no token is involved), 21,000 unit of gas is needed.
Assuming the gas price is 130 Gwei, you have to pay 130 * 10^-9 * 21,000  = 0.00273 ETH.

Yes, rhomelmabini is definitely referring to weekly lottery tickets. Every time you spin the wheel in WOF game, you have 1.3% chance to win 5000 weekly lottery tickets.
The maximum number of golden tickets you can get is 50 and the probability of winning that is only 0.0025%.

You can back up the google authenticator.

To do so,
    1. Tap on menu button (the 3-dots button) at top of the screen.
    2. Select "transfer accounts".
    3. Select "Export accounts".
    4. Check the accounts you wish to back up and tap on "Next".

After steps above, you will see two QR codes. Keep them in a safe place.
Since your phone won't allow you to get screenshot, you need to take a photo from the screen using another phone.
(It's more safe to use an air-gapped phone for taking the photo and print QR codes.)

As you are referring to a full node, you are 100% correct. A full node verify all transactions and blocks.
But I don't think a node (I mean a non-full node) verify all transactions inside a block one by one. A non-full node relies on other full nodes instead of verifying all transactions one by one.

Am I right? Someone correct me if I'm wrong please.

I didn't say nodes don't verify transactions. I said that nodes don't confirm transactions.
I didn't say only miners verify transactions. I said that only miners confirm transactions.

"Verify" is different from "confirm".
