You are right. That's not possible.
When it comes to legacy addresses, there are two legacy addresses derived from a single private key. One is derived from the uncompressed private key and the other one is derived from the compressed private key. But there's only one nested segwit address and that's derived using the compressed private key.

Are you sure that's a bitcoin private key? Maybe, it's an altcoin private key.


A private key starting with 5, K and L and including 51 or 52 characters is a WIF private key. That's the most common format of a bitcoin private key.
A private key can have other formats as well. For example, a private key can be in hexadecimal format and includes 64 characters (0-9 and A-F) or it can be a mini private key and includes only 22 or 30 characters.

It will be possible to generate the same addresses in the future. Electrum's source code is public and even if there's some changes in the next updates, it will be still possible to generate the same addresses.
For detecting errors, BIP39 seed phrases include a checksum and you should always use a seed phrase with correct checksum, because it's standard and it's accepted by other wallets as well. I would never recommend using a non-standard seed phrase.

I highly doubt that number is correct (even if those how have hidden their online status aren't considered as online)
According to loyce.club, more than 2100 users have made post in the past 24 hours. The number of users who have been online in the past 24 hours and the number of users who have been online per day on average should be much bigger.

Electrum allows you to import a seed phrase with less than 12 words. It would display a message saying checksum is failed, but it generates the wallet with correct addresses successfully.
Electrum even allows you to generate seed phrases including less than 12 words using console tab.

No one has forced you to trade and there's a very simple and working solution for you.
Do not trade with the money you can't afford to lose. No one is responsible for your losses other than yourself.

Today's decrease (not dump) in bitcoin price was probably due to the panic selling caused by FTX crisis which shouldn't have any effect on stock markets.
We shouldn't expect FTX crises to cause a drop in Nasdaq index.

In the past months all the markets have been affected by FED's decisions on raising interest rates. I think that's why we have seen same movements in bitcoin and stock markets and I don't think that will change in the coming months.

Your guess is wrong. They pay the network fee with the native coin and charge you using another token. That's exactly how centralized exchanges work.


There is no guarantee that they won't freeze your transactions.
As already mentioned above by other users, they have full control over your fund and can do everything with that. It's possible that they ask you to verify your identity at any time.

I haven't tried the wallet in question, but its seems to be same as other custodial wallets. They are the real owner of the fund and instead show you a number as your balance.

From my understanding from OP, Poker Player is going to pay the winner using the fund which is now in a casino. So, he has to pay the casino withdrawal fee.
Now he is asking whether he should pay the winner from the casino directly or withdraw the fund to his own wallet and then pay the winner.

Each time you spin the wheel, you actually get a random number between 0 and 1 billion. That number determines your prize.
To decrease the chance of winning big prizes, the changed the prize table.
For example, before the changes, for winning 5000 reward points, you needed a number between 320,000,000 and 333,274,986. Now you need a number between 331,308,320 and 332,308,319.

I always make any payment from my own wallet, so I can be able to prove that I am the one who made the transaction.


Assuming that the network status will be as it is now and you will use a segwit address, you will be able to make the second transaction (the one from your own wallet to the winner's address) with paying less than 150 satoshi as transaction fee. That should be nothing compared to casino withdrawal fee.
Just note that you should use a non-custodial wallet that allows you set the fee rate yourself and with 1 sat/vbyte, your transaction may take a long time to be confirmed. (You may have to pay more fee if you want your transaction to be confirmed faster.)

The rolls aren't predetermined.
The house doesn't know the outcome before you click the "play" button.

Wrong.

They have decreased the chance of winning big prizes, but that doesn't mean the game isn't provably fair.
"The game is provably fair" means that you know how the outcome is determined before you play and you can verify the rolls. In a provably fair game, there is nothing hidden from the users and there is no way for the house to cheat you.

Since the game is provably fair, the number is determined randomly and each roll is completely independent from other rolls, there is no difference between spinning the wheel of fortune 200 times in a day and spinning it once a day for 200 days.
Also, it doesn't matter whether you play them one by one or play all with a single click.

The chance of winning 50 reward points, 50 lottery tickets and 50 satoshi are equal to each other.
If you have won the 50 lottery tickets prize more than the two other prizes, that's just because of your luck.

That's not something new. It's been a long time since the chance of winning each of 500 lottery tickets, 500 reward points and 500 satoshi prizes has decreased from 2% to 0.2%.
Also, the chance of winning each of 5000 reward points and 5000 satoshi is 0.1% and the chance of winning 5000 lottery tickets is 0.2%.


From freebitco's website:
"Winners will be declared and paid out within 48 hours of the event ending."

To see your addresses, you can simply tap on the 3 dots button at top right corner of the  screen and select "Addresses".
You can also go to "Receive" tab and select "Request", so electrum display a new address.

What do you mean by verifying address? Do you want to verify a message? If so, signing and verifying messages isn't supported by the mobile version of electrum.

You don't have any option other than using centralized services like banks for holding your fiat. When it comes to cryptocurrencies, you have the option to keep your coins in your own non-custodial wallets and be your own bank.
Exchanges have been created for trading cryptocurrencies, not for holding them and it's normal that they want to make profit.

I don't think that's bad.
It encourages people to withdraw their funds from the exchanges and keep them in their own (non-custodial) wallets.
Why should users keep their coins on exchanges if they don't want to trade? Exchanges shouldn't be used as wallets.

The entropy provided by the 24 word BIP39 seed phrase is 2¹²⁸ times the entropy provided by the 12 word BIP39 seed phrase.


You didn't understand BlackHatCoiner correctly.
If you lose the same number of words in a 12 word seed phrase and a 24 seed phrase, brute-forcing the 24 word seed phrase would be easier.

Let's say you have 23 words of a 24 word seed phrase and 11 words of 12 word seed phrase.
On average, there would be 8 possibilities for the missing word of the 24 word seed phrase and 128 possibilities for the missing word of the 12 word seed phrase.

If you miss the whole seed phrase, the number of possible combinations in the 24 word seed phrase would be much higher.

That's because they charge you extra fee.
When you withdraw bitcoin from a custodial service like coinbase, you pay the fee to the service instead of paying miners directly. Custodial services usually charge you more than the fee they pay to miners.
If you use a non-custodial wallet which allows you to set the fee rate yourself, you can make bitcoin transactions with much lower fees.
