I read some old threads about lost Bitcoins ND this question has been on my mind ever since
If the lost Bitcoins were for instance recovered will the price of Bitcoin drop because in theory it would affect the amount of Bitcoin in circulation which will lower it's price . I saw in those threads that lost Bitcoins are considered a donation to the Bitcoin network. so if my theory is correct then we should be happy those Bitcoins were lost.
A donation to the network, it is a beautiful statement, but it will not always the truth. So a bitcoiner should make a hard decision to "destroy" his bitcoins, because he knows they are limited. Just think about it and you come in a short time to the thought "no I do not". so a donation is very nice to say, but I believe it in very few cases. There is for example this address here, recently weéder bitcoin arrived with the designation "Mt Gox Hacker":
