₿ Shortest formula to compute the total supply of Bitcoin

First formula draft

=SERIESSUM(2,0,-1,{210000*50,210000*50,210000*50,210000*50,210000*50,210000*50,210000*50,210000*50,210000*50,210000*50,210000*50,210000*50,210000*50,210000*50,210000*50,210000*50,210000*50,210000*50,210000*50,210000*50,210000*50,210000*50,210000*50,210000*50,210000*50,210000*50,210000*50,210000*50,210000*50,210000*50,210000*50,210000*50,210000*50})

Best optimization after some iterations 💚

=SERIESSUM(2,0,-1,SEQUENCE(33, 1, 210000*50, 0))

Output = 20,999,999.9975553 | to get this ouput, need to display 7 digits after the decimal point on Excel/GoogleSheets
