# This is a Linode StackScript https://www.linode.com/stackscripts/ for deploying
# a Bitcoin node optimized for use on a VPS, for learning or testing purposes.

# WARNING: Don’t use a VPS for a bitcoin wallet with significant real funds — see
# http://blog.thestateofme.com/2012/03/03/lessons-to-be-learned-from-the-linode-bitcoin-incident/
# it is just very nice to be able experiment with real bitcoin transactions on
# a live node without tying up a self-hosted server on a local network. I’ve
# also found it useful to be able to use an iPhone or iPad to communicate via
# SSH to my VPS to do some simple bitcoin tasks.
