Dear SEC, 

I’m writing to support the conversion of Grayscale Bitcoin Trust (Symbol: GBTC), currently the world’s largest Bitcoin fund, to the first Spot Bitcoin ETF in the United States. 

***self custody is a concern as well as inability to taje advantage of having bitcoin in a tax advantage account. My retirement funds can only be invested in overcrowded index funds. You are adding to the pain of the working class. Approve spot bitcoin ETFs. 

Sincerely, 
Cynthia McKiernan 

Phoenix, Arizona
