Has anyone studied the rate at which bitcoin is lost forever? I imagine daily there's a wallet lost, HD destroyed, someone with private keys dying and btc permanently lost. Point is there is a much smaller supply of usable btc than what's actually reported in circulation. I wonder how that plays into the longevity of the project over time...
