On the one hand, blockchain allows users to transfer assets without traditional banking intermediaries. But on the other hand, does a successful on-chain transfer necessarily mean that the money can smoothly enter real-world economic activities? I believe the real issue worth exploring is the technological boundaries. While crypto assets like Bitcoin can be transferred peer-to-peer via blockchain networks, actual economic activities also involve fiat currency exchange, commercial banks, trading partners, commodity trade, and regulatory requirements. The technological openness of a payment tool does not automatically exempt users from real-world economic and legal constraints; this boundary still needs to be explored and developed.
