Report: At least 1.6 million bitcoins may be permanently lost

Last month, the 18 million bitcoins were dug up. As of now, the total circulating supply of Bitcoin is 18,056,962 BTC. According to further research by CoinMetrics, the actual supply of Bitcoin is much lower than this data. According to statistics, at least 1.6 million bitcoins may be permanently lost, which means that the actual liquidity of Bitcoin (over 16.4 million) is far below the level it should be.
