Bitcoin's real max supply isn't 21,000,000 BTC. It's 20,999,999.9769 BTC, because each halving right-shifts the reward and drops fractional sats.
Check it yourself in Python, mirroring Bitcoin Core's GetBlockSubsidy (src/validation.cpp):
s, h = 0, 0
while (5_000_000_000 >> h) > 0:
s += (5_000_000_000 >> h) * 210_000
h += 1
print(s, h) # 2099999997690000 sats, 33 eras
Last block that pays any subsidy: 6,929,999 (around 2140).
ES: El suministro maximo real de bitcoin es 20.999.999,9769 BTC, no 21 millones: cada halving descarta las fracciones de sat. El codigo de arriba lo comprueba en segundos.
