I was reading about some cases of people who had many BTC at a time when it has low or no value at all, and didn't care about it, so they eventually lost their security phrases, or hard wallets and now it is lost probably forever.
I've read that the amount that is considered lost can be up to 5 million BTC. That is about 1/4 of the total amount available.
Knowing that BTC has a limit, and we're getting there soon, isn't it possible to have some compensation for those lost BTC?
Something like adding more BTC in an equivalent amount for those lost BTC, or something similar.
Would it be positive for the currency or could bring some caos?
No, there is no way it can be fulfilled. Because your bitcoin is lost if you can recover then definitely try it. But it will never be possible for someone else to compensate you for this
If such a compensation system were in place, the value of Bitcoin would be much lower. Bitcoins have the highest value because lost bitcoins are not recovered.
I believe the OP did not know the mechanism of operation of Bitcoin, that is the only reason why he can be asking that question. If the structure and the operating system are left as it is now and based on the initial plans, then nothing can be done as the OP wanted and your advice will be so correct in that regard. Well, all hope is not lost yet, we can only say that we can talk with the present mode of operation, but later in the future if Satoshi shows up again, maybe there can be some upgrades, addition and subtraction and unbelievable things that people did not believe is possible and also which people are clamouring now but for unheard.
Bitcoin is a project like never before and Satoshi had his plan though the plans are now known to be very faulty, and that is why projects like Ethereum are getting more relevance if not for the pioneer status of Bitcoin that is helping it. For now, we should enjoy it while it lasts and the Bitcoin you lost is lost forever since it is a decentralised system. No way such can be recovered, not even with Satoshi's intervention in this current Bitcoin system since it is an open-source, nothing is hidden.
