crypto coins review

The CoinExams (CE) score is calculated based on the sum of points given for each exam. Each coin starts with 10 points and deductions are made based on each exam result: low, medium, or high, represented by colours red, yellow, and green, respectively.

Low results in half (0.5) point deduction and yellow results in quarter (0.25) point deduction. The calculation method is updated from time to time based on a number of factors including the addition of more categories, which have to be factored in the score. If two or more coins have the same CE score, the one with lower fees ranks higher.

Coins get additional one (1) point deductions for failing critical exams:
- cost more than EUR 5 to transfer
- transfers take longer than 15 minutes
- no hard cap or supply less than 10%
- annual inflation is greater than 10%
- non scalable algorithm, e.g. not PoS
- less than 25 validator nodes
- actual transfers per sec below 0.1
- unclear metrics, i.e. represented by "?"

Transfer delay in seconds is determined by the time it takes to add one block to the blockchain multiplied by the number of confirmations required by Binance for new deposits to be fully confirmed and available for withdrawal. If the coin is not on Binance, KuCoin data will be used, otherwise the block-time is multiplied by ten (10).

Transfers per sec are not the maximum network capacity (max. TPS), but rather the actual number of transactions carrying funds at the time of data update. Transactions with zero coins or negligable value (<EUR 1), e.g. contract creation and token transfers, are not considered.

These measures are taken to avoid inflated numbers that could misrepresent the actual number of users or the economic activity happening on the network. For the same reason, the number of addresses/wallets on the blockchain is not considered as a metric in the utility score calculation, although its estimate is stated whenever available on the coin page.

Sovereign wallets (third-party wallets) support is determined based on Atomic, Guarda, and BitKeep wallets support. Retail payment gateway support is checked if CoinPayments, NOWPayments, or Coingate support the coin, and check by default for fiat currencies.

Verified means the blockchain has accessible open source nodes to validate the blockchain, e.g. hosted on GitHub. This allows the blockchain functionality to be permissionless. That is it does not require approval or maintainance from a central authority.

Yes, new coins can be added to the list, if they fulfill the following five (5) points:
1. Not a stable coin
2. Not a secondary token
3. Not a layer two solution
4. Available on Binance or KuCoin
5. Daily trading greater than BTC 5
