$0.03

If you don't have a local node (its highly recommended to have a local node for use of this library), you will need to get the develop version of `piston` installed, to get the automatic fallback to remote node (new feature in python-steemlib, not on master yet).

Just run this after installing steemtools:
```
pip install --upgrade --no-deps --force-reinstall  git+git://github.com/xeroc/piston@develop
pip install --upgrade --no-deps --force-reinstall  git+git://github.com/xeroc/python-steemlib@develop
pip install --upgrade --no-deps --force-reinstall  git+git://github.com/xeroc/python-graphenelib@develop
```

Hmm any idea what could have gone wrong? I have a fresh Ubuntu 16.04 64bit + pyenv named pysteem:

Good catch. Try `for event in Blockchain().replay(start_block=1)`

I have been refactoring a lot today, and I forgot that the blocks start at 1 (default is 0). Will push a bugfix update out asap.
Edit: The bugfix is out,  `pip install --upgrade steemtools`

Ok, I looked around and can say that this is an **extremely useful and powerful toy**. Double upvote.
