def main():
    screen.enable_display(True)  # just in case
    screen.clear()  # just in case
    screen.home()  # start at inital position
    while True:
        showCryptoStats("bitcoin")
        showCryptoStats("ethereum")
        showCryptoStats("litecoin")
    except KeyboardInterrupt:  # <-- where is the `try`?
        screen.clear()
        screen.enable_display(False)

You are missing the try in the try/except. I wasn't sure whether you intended to have the while loop inside of the try/except or if you just wanted the three showCryptoStats calls inside but either way, this doesn't work.

Just in case you don't know, I have created snap package for Cryptowatch and it was (no idea how) the most popular package in November. Please, ignore the fact that I have created it in 1st of December… ;)

Description:

I'm new to this cryptowatch script, and I have no clue on how to actually create that portfolio file, what format it should be in. IMO a little bit of documentation would add a ton of traction to this script.

I tried to edit the configuration, but it's little to no use: having to supply one address per crypto is pointless as most people will have several receive addresses, and also I don't see how to add cryptos (Stratis, Peercoin, Dogecoin, IOTA, ADA all seem to be good candidates). A small doc about how to add an API endpoint allowing to monitor this or that would be great.

Hi, since yesterday, I thought it was an update, I can't start de application. I'm on ubuntu 16.04 LTS and this is the message:

python3: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.25' not found (required by python3)

Nice app! Thanks for your work!

Can you remove the last 2 columns for user who didn't auth the buy/sell api. It's useless for those who just watch.
