For example, Satoshi Nakamoto happens to mine the first block. The Genesis address created holds about 99.85 BTC and is currently a dormant wallet. There are also speculations that Satoshi might have thousands of dormant wallets as they were used to receive block rewards. By subtracting the amount of Lost Bitcoin from 21 million, it is likely that we are left with an amount lesser than the total supply when unlocked.
According to speculation, we are made to believe that Satoshi owns over 1 million Bitcoin, whereas according to the real time value of the total circulating supply of BTC at the time of writing this post is said to be 19,696,950 BTC, which means if we are to subtract Satoshi's acclaimed 1 million BTC, what will be left for both lost+unlost BTC currently in circulation will be 18,696,950 BTC.

However, according to data about the top holders of Bitcoin, I'm made to understand that;
1. Microstrategy 174,530 Btc
2. Galaxy 17,518 Btc
3. Marathon 13,716 Btc
4. Tesla 10,500 Btc
5. HUT8 9,366 Btc
6. Coinbase 9,181 Btc
7. BLOCK 8,027 Btc
8. RIOT 7,327 Btc
9. HIVE 2,596 Btc
10. Clean Spark 2,575 Btc
11. NEXON 1,717 Btc
12. EXODUS 1,651 Btc
Of which if you are to sum up all the Bitcoins been held by worlds top corporate holders, it gives us only 258,704 BTC,
