I was interested in trying out the "Dollar Cost Averaging" investment "strategy for Bitcoin. There were a couple implementations of that (for instance <a href="https://github.com/0x13a/bitcoin-trading-dca" rel="nofollow">https://github.com/0x13a/bitcoin-trading-dca</a>), but mostly based on CRON jobs.<p>I did not wanted to run this CRON job locally and I don't have free spare server, so I was looking for a cheap way to schedule this purchase task in the cloud.<p>My solution is an AWS Lambda which is triggered once a day via CloudWatch CRON rule and buys €X worth of Bitcoin on Bitstamp.
