The Domino Effect will occur.. where when a country innovates and then succeeds, other countries will follow in the footsteps of that country. IMO.. China, Japan, South Korea, Singapore, and Russia will most likely follow Germany in the future before other countries in the world
You are being very optimistic. While I appreciate the effort but you have to understand that the popular opinions about crypto is not really good in most countries barring a few. While one country may accept and allow its banked usage, other countries may refuse so what you think of a domino might be a mixture of domino vs anti-domino

Truly it would be a bullish trend if that occurs but it is not likely to happen and certainly less likely to happen within a few years.
I agree with you that this new service will bring Crypto to its peak Will gradually support each country and meet decentralized needs. The United States or the United States is launching this system to improve the economy of their country.
LOL nothing really has happened till now except this news from German banks. They may not accept it and stop allowing it to be bought sold in future. Still lets hope for the best.
