Get your taxes done using TurboTax

Oh Boy this was so much fun.

To calculate your cost basis:

A=Proceed amount

B=Bitcoin Per Share on the date you purchased GBTC (as reported on the appropriate PDF from Grayscale)

C=Total $ amount of purchases

D=Total shares owned

A÷(BxCxD)=Cost

AND PLEASE NOTE THERE WAS A 91:1 SPLIT YOU MAY HAVE TO ADJUST FOR DEPENDING HOW LONG AGO YOU BOUGHT.
