There was no update for April 2017. However, for May, there were seven cryptocurrencies added to the spreadsheets. They coins are as follows...
Augur - REP
Gnosis - GNO
Golem - GNT
Matchpool - GUP
PIVX - PIVX
Ubiq - UBQ
Wings - WINGS
I have updated all of the spreadsheets for this month in addition to updating the currency conversion API for the Euro and Yuan spreadsheets. This should prevent any problems with the spreadsheets not loading correctly. If you do run into any problems in the future, please reach out to me using the contact page. The currency additions for February are as follows...
Once again, the February update will be necessary for full functionality of the Euro and Yuan spreadsheets. I am allowing a one month transition period that will allow full functionality for all spreadsheets prior and after the February 2017 update. Beginning March 1st, 2017, all spreadsheets prior to the release in February 2017 will be obsolete.
I apologize for the inconvenience and know that API's should be backwards compatible with new updates, but this change is necessary to allow the site and all spreadsheets to be offered for free. I do not want to have to end up charging users for access to a spreadsheet of their choosing. The older spreadsheets that some of you are still using is far outdated and that API is still calling prices for coins that are either abandoned or lack a large user base.
Thank you for your cooperation and continued usage.
I apologize for the outage over the past ~36 hours. The issue is now resolved.
In this update there will be no additions, but did a lot of slimming down of coins that have declined in marketcap value since my last cleanup in September '15. If you would like any of the removed coins to be added again, please fill out the coin request form.
THE JANUARY UPDATE WILL BE MANDATORY FOR CONTINUED FUNCTIONALITY
To track multiple wallet addresses, you will have to edit the formula from the "Number of Coins" column. You can do this for as many addresses you would like. I'm going to use Auroracoin in my example.
