So if you lose a bitcoin there is no way to recover it, right?.....what happens over time as people misplace/lose bitcoins, is there any mechanism for figuring out how many are actually in circulation, vs how many were created? (and I'm not making a pro/anti argument, since obviously cash gets dropped/lost/burned all the time).
Since there is a hard cap on the number of bitcoin will this be a problem in 10-20 years if it continues to be used (I assume the amount people lose is small compared to the amount total, but I have no idea) or will the satoshi have to be split into micro- or nano-satoshi?
