What are the coin classes?

We classify coins in four categories based on the publicly available information, the development team activity, the vulnerabilities discovered, and the risk of having 51% attacks, among other things. The classes are:


A+: Outstanding top-level coins. There is plenty of information publicly available and they are being actively developed. Bugs are usually fixed fast. Everyone in the crypto world knows these coins. Investment in these coins is considered extremely safe.


A: Top-level coins. There is plenty of information publicly available and they are being actively developed. Bugs are usually fixed fast. Almost everyone in the crypto world knows these coins. Investment in these coins is considered very safe.


B+: Outstanding mid-high-level coins. There is plenty of information publicly available and they are usually actively developed. Most people in the crypto world have heard of them, but not everyone. Investment in these coins is considered safe.


B: Mid-high-level coins. There is plenty of information publicly available and they are usually actively developed. Many people in the crypto world have heard of them, but not everyone. Investment in these coins is considered moderately safe.


C+: Outstanding mid-low-level coins. There is some publicly available information. Most of them are actively developed. Many people in the crypto world have heard of them, but many haven't. In general, their networks work fine, but in some cases, blocks may be slow to be generated. Investment in these coins is considered moderately risky.


C: Mid-low-level coins. There is some publicly available information. They may or may not be actively developed. Many people in the crypto world have heard of them, but many haven't. In general, their networks work fine, but in some cases, blocks may be slow to be generated. Investment in these coins is considered moderately risky.


D: Low-level coins. There may or may not be publicly available information. They are usually not being actively developed, but some of them may be. Very few people have heard of them. Their networks may or may not work, so it may be possible that these coins cannot be moved into or out of SouthXchange reliably. Investment in these coins is considered risky.


E: Extremely low-level coins. There may or may not be publicly available information. They are usually not being actively developed, but some of them may be. There may be considered evidence of scam practices. Very few people have heard of them. Their networks usually don't work properly so in most cases they cannot be moved into or out of SouthXchange reliably. The risk of delisting is high. Investment in these coins is considered very risky.


The following table is a summary of attributes that impact positively and negatively in coin classes:

✔️Working and easy-to-find wallet❌Non-working or hard-to-find wallet

✔️High activity of development team

❌Little or no activity of development team
✔️Active community❌Inactive community
