Good question. A few brief thoughts from my own exploration of this topic:

Bitcoin captures in its very protocol numerous qualities and fundamental principles Scripture exalts: truth, honesty auditability, rules that prevent partiality, etc. In these ways and more, bitcoin is certainly far more in line with a Biblical worldview than fiat.

Aside from having morally sound characteristics and laws, what determines whether it is pleasing to God is the same as anything else, whether it is used within the context of rightly ordered loves. We are to worship Him alone, to love him above all loves. The worship of any lesser thing, no matter how good it is, is idolatry and pride. Bitcoin is good, but if we deify it, our loves are disordered.

Christ is Lord, bitcoin is a wonderful gift of providence, and like all good things it ought to be used faithfully and righteously.

As was mentioned above, Jimmy Song has some great content on this subject. His book Thank God for Bitcoin is an excellent read.
