4. If Germany's crypto tax is lax, I expect this will be copied in some other European countries in the not-so-far future, hence it may not be a bad idea to have a bit more patience and keep the eyes open.
I would find the statement more credible if you had used "I hope" instead of "I expect", which implies a more vain hope. Germany has had a more favorable legislation to cryptocurrencies for many years, and there has not been the copying effect you are talking about, so I do not expect it to happen, except in some specific case perhaps and for other reasons, not for copying what Germany does. In the same way, Germany is called the European locomotive because it has an economic policy different from the rest, which encourages productivity and mass competition, and France with its elephantine state or Italy with its peculiarities do not copy it.
