Bitcoins get lost all the time, lost private keys.
In time we will have fewer and fewer bitcoins, currently it is thought 3-4 million bitcoins are already lost. This makes me sad.
I propose a redistribution method:
>If an address did not have any activity in let's say the last 100 years the address is considered lost and the bitcoins are free to be mined in the next block.
To prevent losing your bitcoins you make sure to transfer them to a new address every 100 years (I am not aware of any other method of "proving" you still have access to an address).
P.S. This would be a change in the consensus mechanism, I know
P.S.S. I am aware of Satoshi's view on this "lost coins are a donation to everyone". Yes, but 4 million is a lot, do we want Bitcoin to still be used 1000 years from now? If this trend continues most if not all bitcoins would have been lost by then.
I think WE in modern societty have a very big problem with time itself, for us 100 years its like an eternity, because in this era we experience so much changes in a very short ammount of time.
But in realty what its 100 years for a coin? or for gold? or fo hummanity in general? NOTHING.
So first 100 years its very ammount of time, second changing that you are changing a lot more things beyond our capacitie of seeing like a lot of people said in this thread before me.
Its a common question we all have because we know its a lot of BTC forgotten, but it is what it is, took that leverage in your favour.
When you heard some talking about 21 million BTC and for that ammount we have scarcity, you think you are a little more wise and you know in fact they are less, so being less the few we have worth more.
Just don't touch other people's Bitcoin regardless of the length of time it is being idle. Anyone don't have the right to move someone's coins, it can be considered as theft since wedon't have permission to move them. Not because we have the authority to modify the code, it is ok for us to do whatever we want and move others people Bitcoin because they are sitting on the address for so long? That is immoral, IMO.
The action of touching other peoples Bitcoin is pointing to centralization so I don't think it is really wise to do that since Bitcoin as we all know is a decentralized blockchain,
