pick a new fresh address each time a withdrawal is made

Unfortunately, due to a limitation in the PHP 32-bits version PHP is unable to derive new addresses from a configured xPub string. This affects all Raspberry Pi's with the exception of the new Raspberry Pi 64-bits ARMv8 architecture.

Add a FAQ question: How do I get notified when there is a new release of Bitcoin-DCA?

1. Click the watch button on the repository page on Github
2. Select Custom
3. Mark the checkbox 'releases' and click Apply

Now you will get a notification when there is a new Bitcoin-DCA release so you know you can upgrade your installation.

I'd like to use Bitcoin-DCA using the funds that are present on my account on the Binance exchange.

Describe the solution you'd like
I am able to connect Bitcoin-DCA using Binance(.com) API credentials

@Jorijn I ran into this error:

configure: error: rtnetlink.h is required, install the linux-headers package: apk add --update linux-headers
ERROR: `/tmp/pear/temp/xdebug/configure --with-php-config=/usr/local/bin/php-config' failed
The command '/bin/sh -c apk --no-cache update     && apk --no-cache add autoconf g++ make     && pecl install pcov xdebug     && docker-php-ext-enable pcov xdebug' returned a non-zero code: 1

I managed to get it to build again by specifying the xdebug pecl version:

# php code coverage & development
RUN apk --no-cache update \
    && apk --no-cache add autoconf g++ make \
    && pecl install pcov xdebug-3.1.5 \
    && docker-php-ext-enable pcov xdebug

I am not certain whether this the correct fix or the correct version (3.1.5) though.

Someone opted the idea to let Bitcoin DCA report how your DCA strategy is performing. Ideally the app would write the transactions to some sort of database and when the user would request statistics, fetch the current price and show how much % the user has progressed.

Hello Jorijn,

First of all, thanks for making this script available! And I used your affiliate link on Bitvavo.

Unfortunately, I am getting an error running this command on RPi:
$(command -v docker) run --rm -it --env-file=/home/pi/Docker/bitcoin-dca/.bitcoin-dca ghcr.io/jorijn/bitcoin-dca:latest withdraw --all --yes --no-ansi

Error:

PHP Fatal error:  Uncaught TypeError: Argument 2 passed to Jorijn\Bitcoin\Dca\EventListener\XPubAddressUsedListener::__construct() must be an instance of Jorijn\Bitcoin\Dca\Component\AddressFromMasterPublicKeyComponent, instance of Jorijn\Bitcoin\Dca\Component\ExternalAddressFromMasterPublicKeyComponent given, called in /app/var/cache/container.php on line 509 and defined in /app/src/EventListener/XPubAddressUsedListener.php:28

I already found an issue with a similar error but it was related to Kraken.

Thanks for helping me!

Running this command on RPI4 results in an error:

docker run --rm -it --env-file=/home/xxx/docker/bitcoin-dca/config/bitcoin-dca.conf jorijn/bitcoin-dca:latest withdraw --all

In KrakenClient.php line 77:
EGeneral:Invalid arguments

Describe the bug
Some .. code-blocks are not visible in the Documentation.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://bitcoin-dca.readthedocs.io/en/latest/xpub-withdraw.html
2. Scroll down to Verifying the configured XPUB
3. See no code blocks

Expected behavior
A clear and concise description of what you expected to happen.

Is your feature request related to a problem? Please describe.
As a German resident, I'm unable to use Bitcoin-DCA with the Kraken exchange. They require me to accept a separate "trading agreement".

Describe the solution you'd like
I'd like for Bitcoin-DCA to signal Kraken I have accepted the trading agreement.

Additional context
Information about implementing this can be found here:

• https://support.kraken.com/hc/en-us/articles/360036157952
• https://support.kraken.com/hc/en-us/articles/360000920026--Trading-agreement-required-error-for-German-residents

First and foremost: Thanks a lot for this great dca solution!
But since you can always make a great tool even "better", I'd like to address the following feature request:

It would be great if we could dca more coins than "just" Bitcoin using your solution.
In a "best case scenario" the supported coins would be those enlisted within your integrated Exchanges.

With this change, I would like to be able to:

• DCA using the Kraken exchange
• Use other base currencies than EUR

As a user, I'd like to execute a wizard subcommand which will ask me several questions what I would like to accomplish using the DCA tool. After these questions, the tool will test and verify the created configuration and help me where I should put it and what the contents should be.

Probable questions:

• Which exchange would you like to use
• What is your API key
• What is your API secret

Describe the bug
Calculation for Access-Window header on Bitvavo is wrong on 32-bits PHP systems.

To Reproduce
Steps to reproduce the behavior:

Execute echo time() * 1000.

Expected behavior
I expect an integer of length 13.

Screenshots

Platform (please complete the following information):

• OS: Raspbian ARMv7

Additional context
The Bitvavo connection is failing because the Bitvavo-Access-Timestamp header is incorrect.

Describe the bug
The documentation page for XPUB is missing its code samples, making the steps impossible to reproduce.

(I was able to find the needed code samples by editing the file on Github, so all good for me)

To Reproduce
Steps to reproduce the behavior:

1. Go to https://bitcoin-dca.readthedocs.io/en/latest/xpub-withdraw.html#verifying-the-configured-xpub or its Git counterpart
2. See the page is missing all its (code) samples.

Expected behavior
See all (code) samples as all the other documentation page.

Hey, would like to use the tool, but I have a love-hate relationship with Docker.

If I am the only one who'd like a standalone version, then ignore me, but I would really like to be able to run dca without needing docker ;).

Wonder what you think.

I need to think of a way to alert the user that a new version is available. Maybe something with JSON file on Github and a tiny alert when a command gets executed, or a separate command check-update.

When setting up multiple lines in crontab, repeating $(command -v docker) run --rm --env-file=/home/bob/.bitcoin-dca ghcr.io/jorijn/bitcoin-dca:latest [arguments...] is annoying and error prone.

Proposed solution
I'd recommend to add to the Tips section of the docs file cron examples how to create a shell script file to reference in the crontab and pass the arguments from the crontab to this shellscript.

Describe the bug
With Bitcoin-DCA 1.2.2, the container is unable to resolve any URLs and therefore is unable to communicate with any external exchange API.

To Reproduce
Steps to reproduce the behavior:

1. Pull 1.2.2: docker pull jorijn/bitcoin-dca:v1.2.2
2. Run against any exchange: $ docker run --rm --env-file=.env jorijn/bitcoin-dca:latest balance

Expected behavior
I was expecting Bitcoin-DCA to function like before. Being able to communicate with external exchange APIs.

Screenshots

pi@raspberrypi:~ $ docker run --rm --env-file=.env jorijn/bitcoin-dca:latest balance

 [ERROR] Couldn't resolve host name for
         "https://api.kraken.com/0/private/Balance".

Platform (please complete the following information):

• Raspbian 32-bit
• Version 1.2.2 of Bitcoin-DCA

Additional context
It looks like this particular bug is only affecting people on 32-bit ARM architecture (Raspberry Pis). I tested it on my 64-bit Raspberry Pi and was unaffected.
