I believe bitcoin will only be recognized and adopted around the world if and only if it is legalized by world's governments.
If there is way to convince the governments of the benefits of bitcoin and it is legalized, only then can it be recognized all over the world.
Another way bitcoin can be recognized is if more major companies (online stores like amazon and Aliexpress and other companies) accept bitcoin as means of payment.
Whichever way, the stage we have gotten to in just this year alone is a stage that no one could have imagined we would have gotten to as soon as this and that makes me so optimistic that bitcoin is ready to give the world what they have never seen before.
