You are right the “risk-free rate” is the best metric for understanding time value of money.
I think the “risk-free rate” today is more risky than it used to be so I have a hard time calling it risk free. That’s probably a me problem more than anything 🤣
I will have to use the risk free rate when we go through a DCF. I am not looking forward to it because calling any government bond risk free may not go over well in crypto world 😆
