Dear SEC, 
I write to you as a GBTC shareholder, in support of the conversion of Grayscale Bitcoin Trust (OTCQX: GBTC) to an ETF. 
An ETF would provide better pricing tracking the underlying asset. Reduce the fees associated with the product and future liquidity opportunities. 
I’m writing from Colorado. Thanks for the opportunity to encourage the SEC to approve the conversion to an ETF
Sincerely, 
Eric Gricus
