No, it's not. Even a coin that is emitted one per second forever is disinflationary. Not only is the yearly supply inflation rate perfectly predictable (unlike fiat), it also steadily converges toward zero (again, unlike fiat). In the long term, the difference between finite and infinite supply is negligible as long as the yearly supply never increases [1].
