Well you know if normal currencies are lost, the CB will just print more, thus decreasing the value of lost coins to replace them with fresh circulating ones.

In BTC all supply is fixed, or atleast ithas a hard cap. I would be interesting that after 1 million years only 1 bitcoin would be in circulation, because everyone else would have lost their private keys.

And that 1 Bitcoin would be worth the entire Planet's money/wealth
