Hello,

How does electrum (or any other wallet) compute the optimal network fee for a bitcoin transaction ?
Or how does this website https://bitcoinfees.earn.com/ compute the appropriate estimate fee ?


I know that you need to take in consideration the number of input/output, and you need to consider the number of unconfirmed transaction, however I want a technical way to compute it myself.



Please do not reply with an API link or any third party service, I would like to do it using opensource tools only.

Hello,


I have 10 BTC in my wallet and I need to send small amounts to various bitcoin addresses.

I can not send in bulk (paytomany) because transactions are automated (daemon - command line).

Due to bitcoin price and the hike in mining fees, I will be sending at 0.0005 btc per transaction (1 output and 1 input).



My problem is : the first transaction wont be confirmed fast, therefor all the other transactions after it wont get confirmed till the parent one is.

Is there any tip to make transaction confirmations unrelated to their parents ? like using the same change address, or sending the coins using a different approach ?

Hello,

*I am gathering some data to build a data-set from different people and wonder if you have a minute to answer my questions :*

You are a Bitcoin / Crypto user, and you are in need to use a service provided by a company, let's say an exchange, or payment processor, wallet or any kind of tool you absolutely need.
For the sake of this example, let's say you can not find any other alternative and you are forced to use THAT service


Question :

- Based on your country of residence, you would trust a company registered in which country ? and why ?

*-> Example : I am American and I would trust a US exchange because of regulations.

Quick question traders if you have a moment, this will help a lot:

1- Which exchange interface do you like the most (UI) ? Why ?
2- Which exchange chart do you like ? Why ?
3- Which exchange do you use / trust more ? and again, why ?



Feel free NOT to support your answer with an argument. Your opinion (even if not popular) can help a lot in this study.

I appreciate your participation.

Hello,
Quick question regarding margin trading on a bitcoin exchange (polo or Bitfinex or any other offering Margin trading).

**Scenario :**

*for the sake of this example, we will assume 1 btc = 1000.00 USD. and I will be trading on a USDBTC trading pair*


I deposit 1 btc in my margin account, and want to GO LONG @5x for 5000.00 USD.
I get a loan of 5 BTC from lenders of that exchange to fill my position.


The question is :

If I have BTC in my account, and lender provide BTC for margin trading, how does the exchange execute a BUY order when I open my position if I do not have USD ?

I assume there is some sort of USD/BTC conversion when opening my position and buying btc ?




I would really appreciate a technical answer.

PS : Please please please, do not just paste a link to a FAQ or refer me to the exchange calculator, I have checked before asking here and I need a technical reply, some sort of mathematical equation.

Hello,

I just need few minutes of your time and your opinion on

What name is more suitable for an exchange.

- Bitrav.com
- Bitelk.com
- Bitruby.com
- Bitdoro.com
- Bitzug.com
- Bitsphinx.com

Please, I am not involved in this project, just trying to help a contact of mine on BitcoinMarkets to find a decent name, and I think there is no better than the bitcoin community to get honest feedbacks.

Thank you for your time.
