Answer

True

Work Step by Step

Continuous compounding always earns more than annual compounding for the same principal P, time T and interest rate r: Annual compounding: $$A=P(1+r)^T$$ Continuous compounding: $$A=P\cdot e^{rT}.$$ As $e^{rT}>(1+r)^T$ for any $T>0$, $r>0$, continuous compounding always yields a higher final amount than annual compounding.
