Yes, my understanding is that Bitcoin is halal. However, in my understanding as a layperson, the default ruling for “worldly” matters is one of permissibility; one needs powerful evidence to declare something as forbidden.

I like Bitcoin for multiple reasons but here are a few:

It aligns with a societal need for a reliable store of value without negative externalities, a fair unit of account, a mechanism to counter the concentration of power.

I don’t buy in to the Bitcoin presents an alternative to the current interest based monetary system but I appreciate its appeal when marketing Bitcoin to Muslims.
