Does HBAR have a limited supply?

Could you elaborate on the supply dynamics of HBAR? I've been hearing a lot about it lately and am curious if there's a capped issuance similar to Bitcoin's 21 million coin limit. Is HBAR's supply finite or can it be expanded indefinitely? If there's a cap, what's the total number of coins that will ever exist? Understanding the supply mechanism is crucial for investors to gauge its potential long-term value. Could you please shed some light on this aspect of HBAR?
