You can use ViaBTC fee service, if the fee rate used for your transaction is at least 10 sat/byte (or 10,000 sat/kbyte). The 10,000 satoshi isn't the absolute fee.
OP has surely used lower transaction fee rate and won't be able to use ViaBTC free service. If OP had used the fee rate of 10 sat/byte or more, the transaction would have been confirmed by now normally. Currently, 3 sat/vbyte is enough for a fast transaction.

Mining will be still profitable for many miners.
The block reward was 50 BTC (plus transaction fees) when bitcoin was created. Currently, that's 6.25 BTC (plus transaction fees) which means that the amount of newly generated coins in each block has been decreased by 87.5%. Mining is still profitable while the block reward has decreased that much. It may worth mentioning that total hashrate reached its all time high less than a month ago.

Note that as times goes, we will probably see more efficient mining devices in the market.

The total hash rate will probably decrease after the halving, but it will increase again after a short time. After the halving, blocks will probably take more than 10 minutes on average to be mined, but everything will become normal again after the first difficulty adjustment.
After the previous halving, the total hash rate of network decreased from around 135 Ehash/s to around 85 Ehash/s in 10 days. That was around 37% decrease in the total hash rate. After that, the total hash rate increased again. Now the total hash rate is around 350 Ehash/s. The same thing will probably happen after the coming halving.

With using martingale strategy, you decrease your chance of winning.

Let's say you have 1 BTC and you want to double it in a casino with the house edge of 1%. If you bet your whole balance in a single bet, the chance of winning would be 49%.
If you start with 1 satoshi, double the bet amount every time you lose and set the bet amount to 1 satoshi every time you win, the chance to double your 1 BTC before losing so many times in a row so that you can no longer double the bet amount would be less than 28%.

In the case binance shut down for any reason, we will probably see a (temporary) drop in bitcoin price and a much bigger drop in altcoin's price due to panic selling.
Bitcoin will surely recover after a while. Bitcoin has been around since 2009 while binance was launched in 2017. If binance shuts down, bitcoin will be still the most secure decentralized payment system and we will be still able to make peer to peer transaction without relying on any third party. Bitcoin is valuable due to its advantages like decentralization. Bitcoin isn't valuable just because people can trade it on binance.

If binance shut down, many of altcoins won't survive, since they have value just because they have been listed on binance. But as I said, I don't think it will have any long term effect on bitcoin.

With using a HD wallet, you have multiple addresses and you are surely prone to dust attack if you don't be careful. For protecting yourself from dust attacks, you should use coin control.


Right.
With dust attack, the attacker may be able to link your different addresses together. If one of the linked addresses is known to be owned by you, then the other linked addresses will be known to be owned by you too.

Just to be more accurate:
The 546 satoshi is the dust limit for non-segwit outputs. The dust limit for segwit outputs is only 294 satoshi.

This is the default setting and nodes are free to accept smaller outputs with changing DUST_RELAY_TX_FEE.

The 8 decimal places we have for each bitcoin now is more than enough. But if we want to have more than 8 decimal places for each bitcoin, we have to change the consensus rules through a hard fork.
According to consensus rules, the amount field in a bitcoin transaction must be an integer between 0 and 2100000000000000. (Note that in the bitcoin protocol, we deal with satoshis, not BTC. So, 1 = 1 sat)

You have an unconfirmed transaction and you want to accelerate it using a service that charge you 15,000 dollars for that. Am I getting you right?

Can you share your transaction ID here? (Note that with sharing your transaction ID, you may hurt your privacy, but it has nothing to do with your security.)
If the transaction includes a change, you can accelerate it using CPFP method on your own without relying on any third party.


You can use ViaBTC free service only if the fee rate used for the unconfirmed transaction is at least 10 sat/byte.

You can bump the fee only if the original transaction has been flagged as RBF. I doubt exodus makes RBF-enabled transactions.

All depends on your luck. To me, solo mining is more like gambling.

To know the chance of finding each of blocks, you can simply divide the hashrate provided by your mining equipment to the total hashrate of network.
Currently, the total hash rate of network is around 350 EH/s.

If you are miner and you can mine a block, you can include such a transaction and there is nothing preventing you from doing that.
Dust limit is not a consensus rule and any node can have its own dust limit. The amount I mentioned above are set by default.

Note that miners are free even to include transactions not paying any fee.

First of all note that you can't make a bitcoin transaction sending 1 satoshi. Such an output would be considered as dust and nodes would reject your transaction.
For a legacy output, the dust limit is 546 satoshi and for a segwit output, the dust limit is 294 satoshi.

Secondly, the confirmation time doesn't depend on the amount your set at all.
Miners prioritize transactions based on their fee rate (sat/vbyte). So, the confirmation time depends on the fee rate you used for your transaction and how congested the network is.

Take note that the 2FA code is generated using a known algorithm. It's not that the 2FA code can be generated only by google.
In the case you have your secret key, you can import it in any other two factor authentication application and get the code even if google authenticator no longer works.

A 12 word BIP39 seed phrase provides 128 bits of entropy. Since a private key provides 128 bits of security, a 12 word seed phrase is enough.
If you want to have more security, you can add a passphrase and keep it is a separate safe place. In this way, even if someone steals your seed phrase can't steal your fund, unless your passphrase is weak and can brute-forced.

If you make a 2 of 2 multi-signature wallet and you keep your seed phrases in separate places, both of seed phrases are required for accessing the fund.
This would provide a same security as a wallet with a seed phrase extended by a passphrase (assuming the passphrase is kept in a separate place, it's chosen completely random and provides enough entropy.)

We don't know who is satoshi and there is no way to know when an unknown person was born. I guess you have taken that date from the misleading information reported on Wikipedia's article.

Anyone who wants to know where that date comes from can read the article published on coindesk.
How Can Satoshi Nakamoto Have a Birthday? The Significance of April 5

As I said in my previous post, you can have a 2FA wallet in electrum, but that's completely different from how two factor authentication work in custodial services like centralized exchanges.

When you set two factor authentication in a custodial wallet or an exchange, the service doesn't allow you to make a transaction or login to your account if you don't enter the correct 2FA code. We can have this feature only on custodial services, since they have full control over users fund. In a non-custodial wallet where you have access to your private keys, you have full control over your fund and we can't have two-factor authentication in the same way as a custodial wallet or an exchange.

You can have a 2FA wallet in electrum as well, but as I said above, it works in a different way. Electrum 2FA wallet is a 2 of 3 multi-signature wallet. This means that there are three private keys for each of addresses and 2 of them are required for making a tranaction. In a 2FA electrum wallet, one of master private keys is stored in the wallet file and one of them is owned by a third party called trustedcoin.
When you want to make a transaction, you have to ask trustedcoin to sign the transaction for you. In electrum 2FA wallet, you have a seed phrase which can be used for deriving two of master private keys and disabling 2FA. So, you still have full control over your fund.  

Moderators can know who has reported the post.
Read the post which has been made by Welsh about this.


And the post made by hilariousandco:

If your device is infected with a clipboard malware, you should format your hard drive and reinstall your operating system from scratch. That's enough to make sure you no longer have any malware in your computer and there is no need to get a new hard drive.

I just left this campaign. Thank you Royse777 for the opportunity.
