Dear SEC,

I join the thousands of other individual investors and well-respected
institutions in urging you to approve the conversion of the Grayscale
Bitcoin Trust (OTCQX: GBTC) to an ETF. For the reasons set forth in
the numerous comments you have already received, failing to approve a
spot bitcoin ETF is both illogical and damaging to individual and
institutional investors alike.

I sincerely appreciate the opportunity to express my views on this
important matter. Please approve the conversion of Grayscale's Bitcoin
Trust to an ETF.

Sincerely,

Christopher Blau
Stamford, Connecticut
