IMHO, in Europe and US, it's almost a deadend now. There are simply almost no use cases for average people and businesses where bitcoin can serve as a better MoE (cheaper and/or faster) compared to cash and banks.

As a SoV, bitcoin is another (risky) investment that fluctuates wildly (ie, it can give you high gains and high losses).

In other countries, bitcoin may be actively used for inter-border transfers, as protection against very high inflation, darknet and for tax avoidance and corruption payouts.

That's my take today.
