The final paragraph of the article regarding the end of Bitcoin by 2040 is a bit weird:
Der Experte nennt ein Datum für das Ende der Bitcoin: Da derzeit etwa 16 Millionen Bitcoin im Umlauf sind, die Obergrenze jedoch auf 21 Millionen festgelegt ist, wird das Ende der Bitcoin-Schöpfung seinen Berechnungen zufolge etwa 2040 erreicht sein.
"The expert calls a date for the end of Bitcoin: Since there are currently 16 million bitcoin in circulation with the maximum supply being 21 million, the end of bitcoin-mining will, according to his calculations, be reached by 2040."
I wonder if the conclusion that the end of block rewards automatically means the end of Bitcoin came from Schamir or from Businessinsider. Either way yet another prime example of a fundamental misunderstanding of how Bitcoin works.
