Germany is pretty interesting
As the OP asked here, I think this refers to the tax benefit - there is no capital gains or income tax charged after hodling Bitcoin (or most cryptocurrencies) for more than a year.
In comparison to some other European countries like Spain, German crypto regulation seems also to be less "intrusive". People in Spain for example have to report a lot of their crypto activities to tax agencies, while in Germany it's only required if you surpass certain thresholds -- although early adopters surpass them easily ...
On the other hand, the Germany sold their Bitcoin, so they clearly aren’t betting on it.
That were confiscated Bitcoins and they can't do what they want with them without a dedicated law or decree.
I didn't vote in the poll because of the four countries listed, most have advantages and disadvantages. I had first looked at Singapore but its regulation seems to be quite similar to the US and Europe. The EU countries have imo gone too far with the AMLR (the MiCa is relatively okay in comparison) and thus I would not vote for Germany nor Portugal. So for me it's a tie between the US and Singapore, although El Salvador and perhaps also other Central/South American countries would probably be even better options.
