Even though you are right that the digitalization of jobs or online work doesn't have any direct link with Bitcoin and it's popularity, we can say that digitalization does make a difference considering the fact that when there are more people available digitally, there will be more people knowing about Bitcoin since we know Bitcoin is digital and someone who is away from the internet as a whole will barely come to know about cryptocurrencies because news and word about them spread online, mostly.

So someone who uses the internet, surfs around in social media platforms, and reads articles and stuff will be more likely to come to know about Bitcoin than someone who is more into offline stuff and never uses electronic devices much or the internet. In this sense, digitalization does make a difference in making Bitcoin more popular over time.

And, with the world moving with a great pace towards digitalization, Bitcoin doesn't need any promotion or anything because the word about it is spreading fast itself.
