I.M.H. O. BTC is difficult to understand and accept in the Western world because:

-Most of us are afraid of hackers, we don't understand the technical side of it.

-there is a massive campaign from normative media to discredit it and mix it up with shitcoins

(media also keeps calling it a risk asset)

- unawareness of what's going on on macro and basic economics

- And a really big percentage of people struggle to make it to the end of the month, so they can't even think about savings . Just surviving is enough for many people in the Western world

Making it safer and more accessible in the technical aspect would increase adoption
