The first points column displays the points the stablecoin scored itself in the categories of usability, availability, acceptance, success, and the stablecoin category. The total column adds the points of the best scoring supported blockchain in the remaining categories to the previous points column for the total points.

The ranking results directly from the points of all the following categories.

Since an exact number of users cannot be determined, the number of existing wallets is considered the best estimate for the number of users. The Fundamental Crypto Asset Score (FCAS) asses the fundamental health of a cryptocurrency and comprises user activity, developer behavior, and market maturity as its main factors. The scores range from A+ being the best to F being the worst. Similarly, the TokenInsight rating encompasses team, project, and ecosystem metrics and ranks cryptocurrencies from AAA to D.

All coins and tokens with a market cap of at least 5 billion, 1 billion transaction volume, and 1 million users obtain 4 points. If one of these three metrics is in the three-digit area in Table 4, the cryptocurrency gets 3 points. If any value is below 100 or the market capitalization is below 4 billion, only 2 points are awarded. Lastly, 1 point is deducted if one rating score is low, which is the case for XRP and DOGE.

Note that ETH has an ASIC-resistant algorithm, which results in a lower hash rate for similar security. For the decentralization table, the nodes represent the number of active validators or miners.

Decentralization: All cryptocurrencies with under 50 nodes like EOS also receive 1 point, while FTM collects 2 for having 64 validating nodes. Coins and tokens with over 100 nodes obtain 3 points for a decent decentralization, while those with 1,000 or more get 4 points. The most decentralized cryptocurrencies like BTC or ETH2 attain maximum points.

Security: For all examined PoS cryptocurrencies an attack would cost a minimum of over 200 million Euros. As this would also undermine the attacker's investment in the cryptocurrency, an attack is improbable. Therefore, all PoS-based cryptocurrencies receive at least 3 points as they are secure. Still, the staked value differs substantially within the sample ranging from 34 billion to 416 million. SOL, LUNA, ETH2, and ADA all have a stake of over 20 billion, making an attack by a single entity almost impossible. Therefore, these four receive the highest number of points possible. All PoS coins and tokens that require an investment of at least one billion for an attack receive 4 points. Achieving control over the Bitcoin blockchain, which has the highest hash rate, would cost an estimated 13.5 billion dollars. Because of the gap in hash rate, BTC is the only PoW cryptocurrency receiving 5 points. It is generally more expensive to conduct a 51% attack on the examined PoS systems.

LUNA transaction fee is actually 0.1%-1%. TRX has a transaction fee of either 1$ or a free transaction if the user has staked enough TRX. All transaction fees are averages and change over time-related to network traffic.

Regarding TPS, the numbers of ETH2, CRO, NEAR, and ALGO are all development goals and are not achieved yet.

Transaction fees: Regarding transaction fees, the majority outside of ETH and BTC are relatively cheap. Therefore, both receive 1 point. ETH2 also receives 1 point, as the transaction fees are not yet known but will be presumably much lower than for ETH. All cryptocurrencies with average transaction costs of under 1$ obtain 2 points while ones under 0.1$ get 3 points. Fees under a fraction of a dollar are assessed 4 points. Coins and tokens with the lowest transaction cost like SOL, EOS, and FTM get maximum points.

Throughput: The ones with a TPS lower than 100 receive 1 point. Throughputs in the range of PayPal, such as BNB and BCH, get 2 points. Cryptocurrencies with a TPS of 1000 or above pick up 3 points while ones outperforming Visa's average throughput attain 4. Best-in-class coins with a five-digit TPS achieve maximum points for fulfilling the estimated requirement of the European Central Bank (10,000).

The points in this category are mainly awarded for blocktime. The recommended number of confirmations is sourced from Kraken or Coinbase.

Visa requires a 2.4-second confirmation time for the entire point-to-point path. Cryptocurrencies that achieve or come close to this speed receive 4 points. ATOM, EOS, FTM, NEAR, and SOL all have a block time of 1 second or below, as seen in Table 7, and attain 5 points. Coins and tokens with speeds slightly slower than Visa get 3 points, while double-digit block times obtain 2 points. BTC, BCH, DASH, LTC, and DOGE receive the fewest points because their transaction speed is in the minutes area.

The availability of native wallets is rewarded with 5 points. ETH and USDC also receive maximum points as they provide many wallet options to the users. The remaining cryptocurrencies obtain 4 points if they have eight or more wallet options, while CRO and MATIC only get 3 points.

The number of markets and FIAT markets is sourced from CoinMarketCap. FIAT markets only include crypto/USD and crypto/EUR pairs.

Availability: Coins with over 40 available FIAT markets from different providers achieve maximum points. A number above 19 earns 4 points, while cryptocurrencies with ten or more markets earn 3 points. ONE and BUSD only receive 1 point for having less than 5 FIAT market pairs, while the others get 2 points.

Acceptance: As every examined cryptocurrency is at least supported by one payment gateway, this results in a minimum of 1 point. It is worth noting that the older cryptocurrencies such as LTC, BTC, BCH, and ETH are more supported than the rest and, in turn, get above-average points. LTC and BTC receive maximum points for being available on 9 and 10 payment gateways, respectively.

Energy consumption estimation in kWh per transaction. ETH has an ASIC-resistant algorithm and hence Medium hardware requirements. Low energy consumption is in place where no estimate could be found but PoS is used.

PoW-based cryptocurrencies do not receive more than 2 points, with BTC and DOGE obtaining minimum points for their energy consumption. All the others pick up 4 or 5 points. Energy consumption of fewer than 0.01 yields maximum points, while the other PoS cryptocurrencies get 4 points, including those without a reported number.
