Online updates for some (crypto) currencies don't work

The common crypto currencies are available to dowload on fx-rate.net, but others aren’t. I’m tracking some of them in KMyMoney and every time I update online prices I have to click away the error messages that appear. I would like a solution to this. Possible ones are:

  • A checkbox in the Online update window to not display a pop-up for each error.
  • The ability to configure a currency so Online updates ignores it.
  • The ability to configure a currency’s Online update source (like a stock)

What do you think?
