I may have played my cards a little high in the ‘application’ by saying that I was in contact with developers and important people...

As a Hive user, you are very close to the developers.
The developer @blocktrades, informs in his blog very thoroughly about the status and progress of his team in improving the Hive code.
On the YouTube channel of https://www.youtube.com/@Hivenetwork, everyone can listen to what the development team is currently working on and what they are planning for the future.
In addition, there are many other developers who make a great contribution.
You can contact any of these developers personally and if your request is polite and for a serious reason, they will respond.
Whether such a small exchange like Bitpanda is interesting for the core developers, I find rather questionable, but you yourself know many arguments in favor of Hive.

Here are a few examples:

• Hive belongs to the community, there is neither a company nor a boss
• Transactions are very fast and cost almost no fees (transactions consume RC, which is “recharged” over time)
• Any Hive user can create another Hive account, there is no need for an authority to decide.
• Nobody has to buy and stake Hive, many functions are available without it
• Hive can be the entry point into the crypto world. If you create good content and share it via the blockchain, you will receive rewards in the form of Hive, HivePower and HBD.
