had a back of the envelop calculation: if the loss rate is 10% per annual, it will take 21 years to reach the 1/10 mark, which can be compensated by moving the decimal point one digit to the right. Not too bad indeed.
I seriously doubt that 10% of gold/silver/platinum bullion is lost every year...
Once people understand that bitcoin is a hard money & a commodity, they will protect it with their lives, the same as they do with normal bullion. Therefore, i think that 10% may be probable for the first few years of bitcoin adoption, and when masses understand the power of bitcoin, the loses will fall to 3% or less.
I agree.
Another difference is that when gold or silver are 'lost' it simply means "expensive to recover, we'll get it later when it's easier or when it's more valuable". It's pretty rare for gold to be transmogrified into lead or something, it usually just gets lost in the water to be found later.
