I have no idea how to calculate what percent my bitcoin holdings are because my net worth is negative. Fucking student loans.
Hmm... interesting. If you divide a number by 0, well, it can't be done. However, dividing a positive number (your btc) by a negative number (your net worth) you get a negative number.
But. Your net worth is calculated by summing your total assets and then subtracting your liabilities.
Maybe you could calculate the ratio of your bitcoin holds to debt.
