BTC inflation is currently higher than USD
Historically, Bitcoin started off as a hyperinflationary mint in order to produce the supply rapidly for a small user group before the general public would be able to access the production methods and before the difficulty settings Satoshi chose would increase the cost of production and reduce the ROI and increase the CAPEX/OPEX dictacted by the BTC mining software and network.
Aprox 4.11% of Bitcoin users (addresses) control 96.53% of all bitcoins in circulation. Also there's a chance that something will make Bitcoin obsolete in the near future - immediately destroying the trade value of Bitcoin, either a new cryptocurrency, a quantum computer or cryptographic breakthrough that would allow theft of BTC private keys or more predictably a bug like what recently happened in the main Bitcoin core wallet client software which allowed a user to inflate the supply of Bitcoins past 21 million and mint more BTC for free.

Then there's the story of Bitfinex, assumed to be a lingering MTGOX scale exit scam using a "stablecoin" which is pegged 1:1 with USD across all other major cryptocurrency exchanges. With no audit, Bitfinex has printed aprox $2,042,257,000 USD as of today. Much of which is alleged to be used by their own accounts to manipulate the levered futures markets.
