there is more important than mass adoption by all e-commerce in the world, namely the legality recorded in the government law and protected by law by all countries in the world
with the official legality, mass adoption will occur and it will increase the interest of new and existing bitcoin users who have known bitcoin from the beginning
really hope that this will happen soon, and we can enjoy bitcoin by using it like we use PayPal or other e-Money to make payments
I see a different point of view. The number one way that would happen is if people are using bitcoin and cryptocurrency. THEN governments will adopt it.
