The rise of fiat-denominated cryptos

Bitcoin is a great invention. It allows people to transact with anyone in the world in under an hour, requires no personal information and is secured by the power of math rather than people with guns. That being said, Bitcoin and a number of other cryptos bring with them the "issue" of being new currencies, not tied to anything else. While we can argue pretty much indefinitely whether that is a good or a bad thing (I personally see it as a backup in case the governments start failing and we need a new gold standard), it is unavoidable that we will see new services and cryptos that take a new spin on this "problem". We might very well soon see the rise of fiat-denominated cryptos.

Hedged accounts

Probably the simplest transition from a Bitcoin into a fiat-denominated crypto can be achieved using hedged accounts. Last year we've seen Locks from Coinapult, and this year CoinJar introduced their Hedged Accounts.

The concept is quite simple - you deposit your bitcoins into a wallet service that enables hedging and you lock your coins at the current price to whatever the service provider offers. They, in turn, promis to deliver you the exact value of the hedged coins based on the future market price. So if you lock your coins to $1, you will receive $1 in the future no matter whether the coins appreciate or depreciate. Moreover, since they provide the service, they get to dictate the current exchange rate, spread and so on.

While you can expect most of the companies that provide this service to actually trade the Bitcoin in and exchange them for the commodities they are hedging, or at least take some options on futures, you should be weary of more risky ventures. I have seen someone trying to set up a company offering hedged accounts without doing any conversion on the grounds of "we believe Bitcoin will appreciate in value, so we will be always solvent" (before they were laughed out of the conversation).

Moreover, I am yet to see anyone offer a hedged account that allows its clients to treat the hedge like an actual, spendable currency. In other words, even if I lock my 1BTC to say, $100, I can't send someone else in the same network exactly those $100 without unlocking my BTC, sending the BTC over and re-locking them and losing money on two conversions. Similarly, I am yet to see a hedging option that allows me to withdraw the underlying currency (so in our example - cashing out a $100 bill rather than some BTC).

All in all, hedged accounts appear like foreign-currency denominated accounts in some banks - while you can ask the bank to hold the currency of your choice, they will dictate the exchange rate and terms by which you can redeem your money. Useful in some circumstances, but not so much if you need a business solution.

Cryptos with a fiat floor

The next step in fiat-denominated cryptos are the cryptos with a fiat floor.

As I discussed back in 2013, when you have a fixed-amount currency like Bitcoin and a potentially infinite currency like USD, you can only establish a floor price for Bitcoin, never the ceiling. That is to say, if I am willing to buy 21M BTC for $21M, you know Bitcoin will never sell lower than $1/BTC, thus Bitcoin will have the floor value of $1. Easy enough. Now, with that out of the way, lets talk about our new ideas.

There are a few examples in this field. a bit obscure Coinaaa (cryptocurrency tied to NOK), Brock Pierce's a bit more well known RealCoin (tied to USD), and the subject of a pretty recent controversy PayCoin.

So how does all of this work? Usually, you would have a premined altcoin that is fully owned by one entity (with maybe a dash left for the miners to mine). That entity would then sell the currency at a fixed rate, whether it's 1 Coin for $1 or anything else. They would also buy the currency back at a similar or even identical price. Provided the company isn't malicious and they keep the required reserves, you would have a nice and solvent fiat-pegged cryptocurrency. It would be better than hedged currencies, since you could actually pay people without having to convert it back and forth.

However, unless the coin supply is flexible, you can only issue so many coins before you run out of the pre-mined amount. Not to mention that mining such currencies puts an extra expense on the coin operators - either forcing them to mine by themselves, or subsidize the miners by backing the mined coins as well.

Moreover, like with all things crypto, the moment you have to trust someone, the moment you can get screwed. As the story of GAW and PayCoin goes, if a business is not committed to its floor from the start and you don't see the money they are backing their coins with, you may end up with worthless coins in your pocket.

All in all, cryptos with a fiat floor is a step in the right direction. While we can pay people in the currency of choice, relying on Bitcoin-like architecture gives us some limits.

Fiat IOUs

This is essentially a more refined model of the previous concept. Instead of premining an altcoin and pegging its value to a fiat currency, we use the flexible model of Crypto 2.0 IOUs. The best example of this approach would be Ripple and its many fiat-backed currencies.

In this model, just like before, we have companies that create their own currencies and sell them for fiat at a predictable exchange rate. Instead of calling them "RealCoin" or "PayCoin", they are simply referred to as USD, EUR and the like. The currencies are created during deposit and destroyed when they are redeemed, thus their supply is more flexible. Just like before - you can use them for payment and settlement.

Generally, it's a model that does away with all the abstractions and works pretty much like a bank. When you put your euros into a Fidor bank you don't suddenly convert them to "20 fidors", they are still Euros in a rigid 1:1 exchange rate. Moreover, in networks like Ripple, those currencies are tradable for any other currencies and allowing for many other neat things.

That being said, the usual caveat applies - we are trusting a company to secure our funds. If the company is insolvent (such as WeExchange), you lose your money. I suppose if the company securing your funds is the actual government issuing the currency (MintChip comes to mind), this point might be getting a bit moot.

All in all, Fiat IOUs are usually better than cryptos with a fiat floor, since their supply is flexible and the currency is not bound by Bitcoin-like restrictions.

Distributed and counterparty-less fiat-denominated cryptos

The last category worth mentioning are distributed and counterparty-less fiat-denominated cryptos (what a mouthful!). Essentially, they are like Fiat IOUs but without a single entity backing the money.

They can take two forms - fiat voting pools and crypto fiat futures.

First approach is based on Open Transactions' idea of Voting Pools. This essentially means that there are multiple gateways / exchanges / backers of a given currency each holding enough money to cover the other parties defaulting. In Bitcoin world, this would be easily achieved with a multisig. In a fiat world, you would probably need some agreement with a bank to guarantee some deposits between multiple parties (similarly to how a central bank protects against bank runs and so on).

While this approach changes the risk model of a Fiat IOU from centralized to distributed, it's still not entirely decentralized. Other than that, it's pretty much a really good solution to create a fiat-denominated crypto.

The second approach is like BitShares' BitUSD. Instead of having a central or distributed entity issuing fiat-denominated cryptos, you have a futures market that creates a new currency that is pegged in value to fiat or commodities. While the process by which this happens is still a bit of an economic magic to me, it boils down to some people going short and some people going long on the BTS-BitUSD exchange rate. This creates the BitUSD asset that can be transferred like any currency. Provided the market works well, BitUSD should be worth about the same amount as an USD.

However, there are some criticisms of BitUSD. First of all, the supply isn't too flexible (if someone wanted to put $1B into the system, the current network couldn't handle it instantly due to the new assets needing to be created first). Secondly, there is a possibility of the market essentially collapsing (if enough margin calls were executed too quickly due to a sudden price swing). Lastly, the asset needs to be exchanged for fiat at an exchange - it can't be directly withdrawn like Fiat IOUs.

All in all, we come to a fork in our road. On one hand, we can have distributed fiat-denominated cryptos backed by multiple entities, or counterparty-less fiat-denominated cryptos. It would be rather hard to refine the concept any further - if a crypto is to be a fiat IOU, someone needs to hold the fiat money to allow you to withdraw it. If there is no counterparty, the crypto is unbounded, but it can't be freely withdrawn.


All in all, it seems like we are only beginning to see what the fiat-denominated cryptos have to offer. In the coming years we will probably see this form of cryptocurrency rise into some popularity due to the stability they offer. While I still hold my Bitcoin and enjoy the rollercoaster ride it is giving all of us, fiat-denominated cryptos might be more appealing to the crypto newcomers.


  1. Fiat denominated assets/currencies will all fail just like the fiat currencies themselves. Wait until every CB on earth will do QE and then we will see how good they are when prices will double every day.
    Let's not forget this:

    1. If the governments are incompetent, their currencies will fail. However, I'm not ruling out the possibility of there being a competent government out there, somewhere, possibly... ;)
