NOT TRILLIONdon't you know how the calculation works? because in the specification it's clearly written

Specifications:
100,000,000,000 Billion Coins
60 Second Block
100,000,000,000 Billion Coins
60 Second Block
so the usual calculation will be 1 Billion = 1,000,000,000 so that's mean the total supply will be 100.000.000.000.000.000.000 Coins
You are NOT taking into account DECIMAL points of 8!!!
// MONEY_SUPPLY - total number coins to be generated
const uint64_t MONEY_SUPPLY = UINT64_C(10000000000000000000); // 100 Billion
