Hey there
since yesterday, the app throws the following error message on some coins:

Probably some API call error, but there was no email or other way to contact you, so I hope you see this eventually!
Hey
Coinmarketcap changed their api path for all coins that's why you got nan.undefined error.
I've released the update 10 mins ago. Mammon should be updated in 4 hours automatically or you can click "Check for updates"
Thanks
