Warning - long post that actually involves economics...
In order to function as a serious currency you need three things : 1. Long term trading faith in the currency, 2. Value stability from day to day / month to month (neither rapidly inflationary nor deflationary), and 3. Liquidity (enough units that it's actually widely usable beyond a novelty currency without shortages "spiking" prices, deflation kicking in or even triggering off a depression). Not only does Bitcoin fail miserably at all three, but real currencies are supposed to be stable not massively change in value up or down. Why do you think the Chinese under-pegged the Renminbi vs the USD? (Hint : Appreciating currencies destroy export economies...)
This is why nothing is priced natively in Bitcoins, it's priced in USD / EUR, etc, and the Bitcoin equivalent is simply accepted then rapidly converted back to USD's (more like a Paypal / charge-card transaction than a "currency"). To price it natively in Bitcoins (vs in USD's) would be the equivalent of a baker selling bread for $1.50 in 2010 then see nothing wrong with $0.000002 "prices" by 2018 whilst the cost of making a loaf of bread / purchasing flour, etc, remains static over 8 years and bread remains priced at £1.10 / €1.30, etc, elsewhere. The currency no longer fulfils its purpose in reflecting reality vs what the actual goods cost to produce from even one week to the next. Literally every good under $2,500 at 2010 BC values would fall to 0.00BC when rounded under the near-universal 2-decimal place retail system. The "currency" would be so totally useless for any stable day to day reference of apparent price vs actual manufacturing cost of relatively static real-world goods that it would be instantly dumped in favor of pricing it in something more stable (if not shatter the illusions behind the "valuations" themselves). Those figures ($0.03 March 2010 to $17,900 Dec 2017) are literally the deflationary equivalent of +59,000,000% inflation over 7 years (ie, "full on" 3rd world banana-republic failed-state territory), and it is utterly laughable people are suggesting this is some "evolution" to fiat changing value by only a few percent per year...
Bitcoin is even more intrinsically worthless than the US Dollar, as every govt-issued "fiat" currency actually does have a lot of intangible backing (Forex reserves, currency swaps, trade demand, and not least the entire national economy / military) which far exceeds "well you can use it for ransomware against hospitals, so there's that!". The "mining" and blockchain merely guarantee that a Bitcoin unit is "legally" valid they don't actually give it any intrinsic value. That's the equivalent of arguing "the US Dollar derives its value from the existence of USD banknote verification machines and accounting ledgers (which exist solely because the US Dollar exists)". Money doesn't derive value from simply not being counterfeit or not govt issued, nor can any currency be "backed" with an aspect of itself via circular logic. That's why central bank foreign exchange reserves hold every currency except their own.
The fact there's a max cap of 21m Bitcoin units (preventing Zimbabwe style hyper-inflation) doesn't make it any more "valuable" than if you created your own private currency and paid De La Rue to print 21m unique high-security notes, then handed them out on the basis of who wasted the most electricity / owned the most expensive GPU's, then destroyed the printing plates and deleted the templates. Exactly the same economics and anti-inflationary effect as "fully mined" Bitcoin without all the absurd intermediate wealth destruction (blowing billions on wasted electricity which unlike physical metal mining, produces zero tangible end product for high industrial demand). The rest is techophiliac novelty bubble hype from those constantly confusing the potential utility of how a blockchain could be mated a more stable future currency vs today's junk economics of hyper-deflationary digital "coins" being some "cure" for mild ordinary inflation usually churned out by over-zealous "gold bugs" and the usual crack-pot prepper / conspiracy theorists and their "The Evil Fed (tm) / Worthless Fiat (tm) / Rothschilds & Rockefellers / Illuminati / The Queen of England is a shape-shifting Reptilian Anunnaki lizard alien from outer space" (no really), that all common sense goes out the window.
If you truly want to hedge against a "post reserve status" collapsing inflationary USD, you buy tangible stuff (real estate / land, high-demand international commodities (oil, wheat, etc), metals, and stocks in foreign companies natively valued in another currency that deal in tangible high demand essentials (utilities, food, etc). Stuff that's either permanently "consumed" or "produces".
Bitcoin is ironically the ultimate in fiat currency when "mining" = GPU's "printing" money from nothing. If mining hardware were 100x less powerful, those who created the coin would have just changed the complexity factor of the mining formula to be 100x easier. If radical quantum / DNA computing was developed tomorrow and we had a 1 trillion fold leap forward in computing power, every existing XXXcoin would be mined out within a very short period and new XXXcoins would spring up with you guessed it - arbitrarily 1tn more complex equations. Deciding XXXcoin should be ASIC resistant is a "fiat" dictat too. All of this is no different to central banks deciding how fast to print. That's why 96% of Bitcoins are "coincidentally" in the hands of the 4% who created them (of course they get to mine all the easy units no different to being Tier 1 creator in any pyramid scheme) - a laughable "decentralized people's currency" 'cure' for exactly the same current 95%/5% "centralized elitist" system, or why the "cure" for paper fiat notes losing value over 100 years isn't thousands of half abandoned / fragmented digital coins variants all suffering from unsustainable runaway +500,000% deflation before their 10th birthday.
tl:dr - Bitcoin is literally the equivalent of a imaginary gold-mine that never produces any gold and whose market cap is 100% self-speculation of maths equations that do not really have any measurable economic value attached to their "solutions" outside their self-justifying circular logic. The key to seeing the fake valuation bubble is not "BC vs paper money" - it's BC vs relatively static everyday commodities and real-world goods and the Bitcoin super-bubble is blatantly obvious when you plot "price of wheat / bread / oil / silver / iron ore / coffee / rice in Bitcoins" and you'll see those exponential speculative bubble curves completely divorced from reality as clear as 17th Century Dutch Tulip Bulbs...
^ Yes and half of it comes from blindly repeating the #1 fallacy of those talking up Bitcoins to infinity - you're mixing up two completely different things : 1. The theoretical advantages of using blockchains in a number of future applications and 2. The absurd punch-drunk la-la-land hyper-deflationary "valuations" of Bitcoin based on perma-liquidity-crisis "economics" being seen as the "second coming" by a few geeks who are good at explaining the potential future utility of blockchains, but totally cr*p at economics...The FUD is thick in this thread.
