Error in utils.py

[SarchB]

Sorry, should probably not raise an issue but rather submit a commit, but don't work with girhub often and short on time.

But I found that coin_id = coin_link.values()[0].lstrip("/currencies/")[:-1] in utils.py should be changed to coin_id = coin_link.values()[0].replace("/currencies/","")[:-1]

I discovered it while running into trouble trying to use your code for currency EOS.

I found that '/currencies/eos' in your code resulted in 'os' as the coin_id, while it should be 'eos'. I thought it was a bug in Python but found it wasn't > https://bugs.python.org/issue5318
