According to Odaily, economist Peter Schiff expressed his concerns on the X platform regarding Bitcoin ETFs. Schiff argued that ETFs contradict Bitcoin's original purpose, stating that it is no longer decentralized or peer-to-peer. He highlighted that Bitcoin in ETF form can be easily confiscated, cannot be used as a payment currency, and is not suitable for cross-border transfers. Additionally, users do not possess private keys, meaning they no longer truly own their Bitcoin.
