Mate, dissenting opinions come from dissenting judgements in court rulings. There was never a judgement in a ruling what constitutes bitcoin so there is no dissenting opinion or judgement.
Edit: name one court in one country that has constituted btc as bitcoin and Im wrong.
Go on, name one.
If you cannot then we can agree that there is no definition legally as to what constitutes bitcoin, right?
*snip unprecedented irrelevant opinion inapplicable to any legal system.
No court in any legal system in any country has ruled what constitutes Bitcoin.
