I built a Telegram bot to search crypto jobs. Feedback?

Hey HN! I decided to geek out and build a simple telegram bot that would help people (individually and in chat groups) search and get notified about latest jobs in the blockchain industry.

You can play with it here https://t.me/cryptojobslistbot

> A brief overview of its modest functions.

In private mode (when you are messaging the bot directly):

  - do `/start`
  - then just type any keyword to search for it. E.g. `developer`
  - you can also filter by location, by typing in `developer in singapore` or `marketing in new york`
  - you can also filter remote jobs by typing `remote` or `remote developer`. That should work

In group setting (when you add the bot to your chat group):

  - do initiate it by typing `/search@CryptoJobsListBot`
  - further on, you should be able to just type `/s developer` or `/s developer in new york` or
  any of the abovementioned commands, but with `/s ` prefix and get your results.

I have not built that many chatbots before, so not sure what are the best practices are. What features could be useful? What can I improve?
