[integration] Blockfolio Signal

Contacted them and here are the answers:
```It looks like we on boarded Bitshares to the Blockfolio Signal platform back in November of 2018, but no one from your team ever logged in or made a post.```

```We currently only have one team member listed for the Bitshares team and they have not logged in or responded to any emails to get them started. Do you have updated contact information for the bitshares team that you would like to provide in order to get them started posting?```

The team member is @ryanRfox I could put myself there if needed to streamline the news into Signal

The issue names Blockfolio Signal and the BitShares team member @ryanRfox but provides no files, tests, or code entry point. Start by verifying the team's current contact and onboarding status with Signal; done means the responsible team member is confirmed and able to post updates.
