Bitcoin as an asset or currency in my opinion is a small difference. The most important thing is that it is legalized in many countries, and then you can already convert as you like.
That is not the most important thing, it is nice to be able to convert our bitcoin to fiat legally, but the one of the greatest things about bitcoin is that it allow to us to carry our wealth without the need of anyone knowing it, for example if you carry with you a credit card and you use it in another country, your credit card company knows that you traveled to another country, if you carry cash you need to declare it if you travel to another country, but if you carry bitcoin no one will ever know it.
