Crypto Autobuyer

Easily and quickly automate recurring cryptocurrency purchases and take profits. Supports 122 exchanges and thousands of markets/pairs. Main usecases are to average-in on downtrends and periodically cash out on uptrends, as the majority of passive investors are highly unlikely to catch exact market tops and bottoms.

Designed to run on Google Cloud Run + Cloud Scheduler and managed using run-marathon, but can be deployed in any environment that supports Python3.

Setup

1. Install run-marathon (python 3.6+)

pip3 install --user run-marathon

2. Create a trade-only API key on your favourite exchange

3. Save your API secret and password (if applicable) to GCP Secret Manager. These will be automatically decrypted and loaded on container startup using Berglas

echo -n 'your-api-secret' | \
  gcloud secrets create api-secret \
    --replication-policy="automatic" \
    --data-file=- \
    --project your-project

echo -n 'your-api-password' | \
  gcloud secrets create api-password \
    --replication-policy="automatic" \
    --data-file=- \
    --project your-project

4. Modify the example run.yaml to fit your needs and then build + deploy

Note: If you want to use a pre-built Docker image, you can echo "FROM ghcr.io/adrianchifor/crypto-autobuyer:latest" > Dockerfile and change dir to the location of the Dockerfile.

Cloud Run, Build, Container Registry, PubSub and Scheduler APIs are enabled. All good!
