PostScarcity:

== Criticisms outdated ==

I've removed two of the criticisms that were added back in December 2012. The first criticism was vague, and the other was resolved as of version 0.3.0.

I've quoted them below for posterity:

---------

* A hasty release of the coin - a whitepaper was released, and very quickly afterwards a blockchain was started, without giving ample time for people to even notice the coin exists.

* The coin's security model is not yet well understood by the community. One exploit is documented [https://bitcointalk.org/index.php?topic=131940.0 in this thread].

---------

Today I added back in the "hasty release" criticism with much more context. [[User:PostScarcity|PostScarcity]] ([[User talk:PostScarcity|talk]]) 18:45, 16 April 2013 (GMT)

Comparison of cryptocurrencies

2013-04-14T20:52:22Z

PostScarcity: Moved PPCoin from Minor to Major, removed Testcoins because it's not on the thread this article is based on, and it has no market cap because it has no market value.

This article aims to list relevant cryptocurrencies, even those too minor to have their own wiki entry. See also [[:Category:Alternative cryptocurrencies]]

It is based [https://bitcointalk.org/index.php?topic=134179.0 on this thread].

= Currencies =

The order / grouping of these coins are still TBD.

[[User:Ripper234|Ripper234]] proposes a grouping of Major, Minor and New by an arbitrary market cap limit. This can be done once the market caps of the alts are known.
* Using market cap will make Tonal Bitcoin a "Major" despite de facto minor usage. Therefore, I suggest finding a different method of categorizing. --[[User:Luke-jr|Luke-jr]] ([[User talk:Luke-jr|talk]]) 05:06, 4 March 2013 (GMT)
