Hello friends, this is my first discussion on the forum, and it's a pleasure to be part of this environment 
I've always had a big question about the bitcoins in wallets that were lost over time. Of course, this is not something to worry about right now, but when will the limit of bitcoins be mined be reached? The circulation limit of the asset will not be just 21 million (value estimated by the system), it will be 21 million minus the bitcoins lost in wallets, which according to studies, is almost 4 million lost coins. This value will probably increase significantly as the year goes on.
What could happen to these lost bitcoins? Will they continue to be lost in "limbo"

The short answer is... nothing will happen to the lost Bitcoins. They will remain untouched unless someone finds the wallets and restores the forgotten passwords/seed phrases. Just like Satoshi once said "all lost Bitcoins are a donation to the community", which means that lost BTC make Bitcoin more scarce and increase it's value. If we add quantum computing to the equation, things become a little bit different. Maybe someone could use quantum computers to brute force the passwords and seed phrases of all BTC wallets. This would make Bitcoin worthless, but I'm sure that the BTC developers will find a way to make Bitcoin quantum resistant.
