HODLers have long advocated for cryptocurrencies as a way to hedge against the inflation of fiat currencies. For example, Bitcoin's supply follows a strict inflationary curve, where a limited amount of Bitcoin is mined every day until the maximum cap of 21 million BTC is reached.
This is the opposite of fiat currencies, where central banks have free reign over the supply of fiat currencies. In indebted nations, such as Venezuela, hyperinflation can occur as central banks go overboard with printing fiat currency to repay debts.
Based on our Inflation Tracker, however, some cryptocurrencies have an inflation far worse than most fiat currencies. The worst offender is Zcash (ZEC) with a shocking annualized inflation rate of ~42%, which implies that its circulating supply increases by 42% annually.
To make things worse, the inflation rates for smaller capitalization tokens, such as NEO and LISK, are not any better. NEO's Da Hongfei has confirmed that NEO project team has been releasing its premined tokens to the effect of a 23% inflation rate in 2018 and is on track for a 18% inflation rate in 2019.
In terms of the store-of-value narrative, Bitcoin still leads the way as the best cryptocurrency for this use case, with a modest ~3% inflation rate. Bitcoin's inflation rate is expected to drop further with the block reward halving happening in 2020.
