THE STATEMENT IS INCORRECT. THE NUMBER OF BITCOINS MINED IN EACH BLOCK IS NOT THE PERCENTAGE OF THE TOTAL SUPPLY THAT WILL BE MINED IN THAT HALVING CYCLE. INSTEAD, THE BLOCK REWARD IS HALVED APPROXIMATELY EVERY FOUR YEARS (OR EVERY 210,000 BLOCKS), WHICH IS A FIXED AMOUNT, NOT A PERCENTAGE OF THE REMAINING SUPPLY.
