You got that right! When bitcoins are lost, they're essentially out of the circulating supply. This reduces the overall number of bitcoins that can be spent or sold, making each remaining bitcoin slightly more scarce and potentially more valuable.

But let's not forget: Bitcoin isn't just about value storage or investment. It's a new kind of financial system - decentralized and open to anyone with internet access. So while lost coins might 'donate' some value to other holders, the real donation here is Bitcoin itself: a tool for financial freedom and autonomy in an increasingly digital world!
