As you can see in the subject section, nearly 4mil (3,789,648 of high estimate and 2,767,468 of low estimate) are lost and bitcoin is in the existence of almost 9 years and right now we're on roughly 3.2mil lost and that puts us on 17mil of max coins to be mined.
Surely, bitcoin can go into decimals and there's still coins to be mined but still with the rising diff and the reward being cut in half, but in the next 10 years let's say that there will be another 1-2mil of coins lost, that will put us on the max number of 15-16mil coins.
Are there any suggestions or works in progress to maybe return coins to it's original miner if the coins weren't touched in the last 10 years? Because by the time that last coin is mined, there will be a lot less coins in circulation (whole coins). Ignoring the possibility of some other coin like ETH replacing BTC.
(article that I've used for numbers:
http://uk.businessinsider.com/nearly-4-million-bitcoins-have-been-lost-forever-study-says-2017-11)
This study was conducted a while ago, I believe? Anyways, I don't understand how this is a bad thing. It simply means the same potential market cap, but less coins to divide it between, thus a higher price per coin...
Now onto the coins be lost. You think 1-2 mil of coins will be lost? The 4 million that were lost earlier, had no value when people bought them. When people buy bitcoins now, they know they have a lot of value.
Those 4 million currently lost Bitcoins came from a time in which Bitcoins weren't worth much more than maybe a couple cents, so if you bought 1000 Bitcoins for $5, you wouldn't really care... I mean... It's just $5, you could make that in an hour working at minimum wage. That's why so many Bitcoins got lost. People didn't care.
However, people would care much more about their Bitcoins now. As Bitcoins have a value of over $10000, I doubt people would just stop caring about their 1000 Bitcoins, as they would be worth $10,000,000.
Anyways, I don't really get what the "lost bitcoins" problem is about.
