According to The Block, Trezor Chief Commercial Officer Danny Sanders stated on June 15 that concentrating Bitcoin primarily in ETFs represents "one of the worst outcomes" for the industry, as it undermines self-custody principles. Sanders noted that of the estimated 6 billion global crypto users, only approximately 10% choose self-custody, with just 12-13 million using hardware wallets.
Sanders argued that adoption barriers are primarily psychological rather than technical, and the industry should focus on improving user experience, education, and backup solutions instead of encouraging reliance on intermediaries like ETFs.
