Scheduling buy & withdrawing

Note

This guide is meant for people on Linux. You can use it on your VPS or Raspberry Pi.

The buy and withdraw command both allow skipping the confirmation questions with the --yes option. By leveraging the system’s cron daemon on Linux, you can create flexible setups. Use the command crontab -e to edit periodic tasks for your user:

Since it’s best to use absolute paths in crontabs, we’ll be using $(command -v docker) to have it automatically determined for you.

Finding out where Docker is located

$ command -v docker
  -> /usr/bin/docker

Example: Buying €50.00 of Bitcoin and withdrawing every monday. Buy at 3am and withdraw at 3:30am.

0 3 * * mon $(command -v docker) run --rm --env-file=/home/bob/.bitcoin-dca ghcr.io/jorijn/bitcoin-dca:latest buy 50 --yes --no-ansi
30 3 * * mon $(command -v docker) run --rm --env-file=/home/bob/.bitcoin-dca ghcr.io/jorijn/bitcoin-dca:latest withdraw --all --yes --no-ansi

Example: Buying €50.00 of Bitcoin every week on monday, withdrawing everything on the 1st of every month.

0 3 * * mon $(command -v docker) run --rm --env-file=/home/bob/.bitcoin-dca ghcr.io/jorijn/bitcoin-dca:latest buy 50 --yes --no-ansi
0 0 1 * * $(command -v docker) run --rm --env-file=/home/bob/.bitcoin-dca ghcr.io/jorijn/bitcoin-dca:latest withdraw --all --yes --no-ansi

You can use the great tool at https://crontab.guru/ to try more combinations.

Tips

• You can create and run this tool with different configuration files, e.g. different withdrawal addresses for your spouse, children or other saving purposes.
• Go nuts on security, use a different API keys for buying and withdrawal. You can even lock your BL3P account to only allow a single Bitcoin address for withdrawal through the API.
