Yup. Hardware wallets are selling out fast.
Why use an ETF when you can hodl your bitcoins at home on a Trezor? (If you can find one to buy).
^paper wallets a thing of the past? :\
Someone who was hoping to click his brokerage site button to buy bitcoin ETF is not going to bother with figuring out how to work paper wallets ... but some of them might take the plunge with an ezy pezy hardware wallet. The demand is still there, it is just very latent, lazy and waiting for convenience. But some of that latent ETF demand will make it to market ... say 5-10% conservatively of the expected, what was it?, $300 million in the first week they were spouting about.
