They should be ashamed of their neighboring countries like Germany that won't tax you for trading crypto. If I live in France, I will definitely move to Germany right now.
Relax. Germany, just like any other European country, does require you to pay tax over your gains, so I am not sure what made you think that they don't.
In some cases Germany does offer quite friendly tax policies concerning certain usage fields, but that doesn't concern your gains. Do you seriously believe that governments will just allow anyone to enjoy profits from trading activities without paying tax? It's a massive income stream for them with how thriving this market is; no way they will not want their cut of that.
I am happy that in case I end up making profits, and I don't see any value in declaring these gains, I can legally avoid paying tax by just spending my coins. Added benefit is that spending Bitcoins helps the ecosystem, so you're doing something good as well.
