Is Bitcoin’s supply cap really exactly 21 million? What’s the true final number, and why isn’t it round? No, not exactly 21 million. The true maximum is 20,999,999.9769 $BTC . The subsidy starts at 50 #Bitcoin and halves every 210,000 blocks. All math is done in whole satoshis with integer division, so fractions get truncated. That cumulative rounding leaves the total about 0.0231 BTC short of a round 21 million. No hardcoded cap exists in the code—just the subsidy schedule. #BTC Price Analysis# #Macro Insights# #Altcoin Season#
