It's been an ugly judicial "first": to arrest someone not for having laundered money or committed any infraction to the law, but for the sole fact of having contributed to the code of a blockchain related tool, that everyone uses under his own responsibility.
On such a basis, when the E.U. will have launched their "digital euro" panopticoin / CBDC, I guess that the HBD coders would better settle in another part of the world than the European Union or the USA.
