That report, however, was published last 2018. Assuming Peter's claim and the several "I lost my btc" threads here are true, what do you think is the current estimate of total lost bitcoin?
Most coins were lost in the early days, so any coins that are being lost now are little more than a drop in the bucket. Also I think it's fairly safe to assume that the majority of people and companies holding significant amount of coins nowadays know better than to lose their password, so the amount of coins being lost over the next few years will probably be rather limited.
