The question it answers
You have built something new, and you are asking which licence it needs. That is the right question, and it cannot be answered from outside the thing itself.
A digital asset is a mechanism. It can be built to carry a yield, hold gold, move money, route revenue, so no existing category reaches for it cleanly until someone understands how yours is actually built.
Until then the licence is a guess, and a guess is what a regulator unwinds after you have issued.
