I think if you really want to invest in the future, invest in the future of cryptocurrency: Nxt.

Mintcoin

A relatively new Cryptocurrency but one that is growing quite rapidly.
Mintcoin is an eco- friendly coin as it only had 5 weeks of PoW mining. After this we switched over to PoS, so that the coins are released based on PoS, using a lot less electricity than PoW coins.
With an active community, multiple exchanges it has been accepted on and new merchants being added often, I believe there is a bright future for Mintcoin. We recently set a bounty, and within a few hours had a Mintcoin multipool!

What we are currently missing is a direct Fiat <--> Mintcoin exchange.
Vault of Satoshi would be perfect for Mintcoin and I believe you will see a lot of trade when added to your exchange!

Thank you for reading, check out our Subreddit: http://www.reddit.com/r/MintCoin/
or join in the IRC chat (https://www.kiwiirc.com/client/irc.freenode.net/mintcoin) where I'm sure someone will help you with any questions you might have

+1 for MINT

NXT!

It would benefit NXT and Vault of Satoshi.

[shmonoff]

NXT/USD

[Komputor]

Agreed, NXT is currently the most promising and innovative piece of crypto tech that just needs to be added!
NXT/USD would be awesome.

[gittygoat]

Gotta add my +1 for DGC  - Digital Coin - Well established with great credentials !

Please add Darkconi (DRK).

Darkcoin is one of the few coins with genuine innovation, here is an explanation for how it works:

http://razorsforex.blogspot.co.uk/2014/02/darkcoin-anonymous-cryptocurrency.html

It deserves a place in Vault of Satoshi not only because it is popular and high volume trade but also because there is real development going on there.  It has a solid supporter base and has kept a relatively stable price compared to many other coins and Darkcoin development is extremely active, with a full time developer.

Also an announcement about Darkcoin beta testing phrase made it to the 'hot' section in r/bitcoin:
http://www.reddit.com/r/Bitcoin/comments/1zde2w/darksend_beta_is_live_now_drk_darkcoin_the_worlds/

This demonstrates a high level of acceptance of darkcoin's usefulness by bitcoiners, indicating it is a respectable coin and worth adding.  I'm sure Darkcoin will be a high volume coin on Vault of Satoshi.

I recommend Darkcoin (DRK) as well, and here is a copy of part of the Darkcoin whitepaper explaining why:


DarkSend

Darkcoin uses  a  decentralized  implementation  of  CoinJoin  in  order  to  anonymize  transactions.  We  named this implementation "DarkSend".

Darksend is a CoinJoin-based, decentralized peer­-to-­peer being implemented into DarkCoin.  Darksend provides  protocol  extensions  to  merge transactions  together  into  larger anonymous transactions.  This system  uses regular nodes and elects a master node to create  the transaction in a decentralized fashion.

DarkSend  is  a  completely  trustless  solution,  where  users  can  achieve  a  high level  of  anonymity.  With the exception of a collateral transaction (explained later, in detail), users run no risk of losing any money at any time.
 
This implementation of DarkSend is available as an option through the client and can be deactivated by the user at any time. The  DarkSend implementation  gathers the required (required for what?) information in multiple stages within each session:

accept inputs
accept outputs
elect a master node
broadcast the finalized transaction
sign
collect or destroy collateral



Defending Against Attack

With the decentralized implementation of Darksend,  there  are  inherent  challenges  to dealing  with  rogue  users who intend (or attempt) to attack the  system.  Such users could modify the software in a way that would cause it to refuse to sign, which would force the pool to reset every round.

To defend against various attacks, DarkSend implements  a collateral system.  A transaction for 0.1DRK  is  made  out  to  the payment  node  to  ensure  proper  usage  of  the  system.  This transaction  is  separate from the  funds added to the DarkSend pool.  If a user submits an input but  refuses  to  sign  or  leaves  at  any  stage,  the  payment  node  will  “cash” the  transaction by signing and broadcasting it.  Collateral transactions require multiple signatures to complete from more than one payment node.

Payment nodes are simply the last node to create a block - specifically, the last block solver and the one before that.  These nodes will monitor DarkSend for misbehavior.  Should any be discovered, the payment nodes will “cash” the transaction by signing and broadcasting it.  This has the added benefit of creating a sustainable income stream - in addition to mining - for miners, while simultaneously protecting the network from attackers.

The collateral transaction is made to multiple payment nodes (the last block solver and the one before that). Cashing collateral transactions require multiple signatures from the user, payment node 1 and payment node 2.

Collateral transactions from a successful DarkSend session are effectively destroyed using a sigScript to make them valid only for a given period of time.


Improved Anonymity

An anonymity enhancement to the generic CoinJoin implementation is added by only allowing inputs of the same size into the DarkSend pools. These sizes are referred to as "denominations" and are in powers of ten (e.g. 1DRK, 10DRK, 100DRK, 1000DRK). This allows the inputs from all users to be virtually the same.  Outputs per user must add up to the denomination size.

Users that send less money than the denomination size will use a second "change" output. These outputs  are  new  addresses not  connected  to  their  identity.  This implementation allows or amounts of any precision to be sent without a negative impact in the quality of anonymity.
 
All users  entering a DarkSend transaction pool have an equal chance of becoming the master node. All participant nodes know which node is the current master by way of an election algorithm. Master nodes also have a collateral transaction that is made out to the payment node, which can be cashed if they misbehave in any way.

In the case where a master node loses internet connection or is a bad actor, the collateral transaction of that node will be cashed and a slave node will be elected in it’s place.  Due to the trustless nature of DarkSend, there is no risk of lost money from the master node being a bad actor as a slave node would be elected to replace the master node and the collateral would be forfeited to the network.


Master Node Election

The election algorithm is a pseudo random deterministic algorithm based on the transaction IDs in the Darksend pool.  By adding up the hash values of the transaction IDs (no apostrophe) and running the value through the X11 hashing algorithm, a pseudo random number is created.

This random number is compared to a target number derived from the txid and pubkeys of the users outputs. The node with the lowest score is elected master while the second lowest score is elected slave. By using this algorithm we achieve a decentralized, tamper-­proof system in which the users can know which node the master is.



Master Node Responsibilities

The decentralized nature of DarkSend requires that one node will decide which transactions are allowed into the pool to deal with network propagation issues. The master node is elected each round to broadcast the finalized transaction, which will then be signed by the DarkSend participants.
 
The participants will be able to check the authenticity of the messages coming from the master node by utilizing ECDSA signatures for all messages after election.
 
Participants in a DarkSend will only sign the finalized transaction if they find that their inputs and outputs are present with the correct amounts. After the transaction is signed and confirmed to be valid, the master node will broadcast the finalized signed transaction and resign.



Improved Pool Anonymity

Users  who  want  to  increase  the  anonymity of the pools can run scripts to “push” DarkSend transactions through the pool by sending money to themselves with DarkSend. This will allow them to take up a space in the pool to ensure the anonymity of other users. If enough users run scripts  like  this  one,  the  speed  of  transactions  and  the  anonymity  of  the  network  will  be increased.


Reward Curve vs Reward Halving

Bitcoin was designed to have a fixed supply with a declining block reward schedule. This makes Bitcoin  a  deflationary  currency,  with  a money  supply  that  grows  a  small  percentage year-over-year. One problem with this approach is the abrupt reward halving that happens every four  years.  This  could  eventually  cause  large distortions  in  the  mining  network  when  the profitability of mining changes drastically overnight.

DarkCoin replaces abrupt reward halving with a reward curve, 2222222/(((Difficulty+2600)/9)^2). The maximum and minimum amounts are set to 25 and 5 respectively. Using this formula, the reward will gradually drop over the following months and years and then provide a steady supply of approximately 1 million coins per year.



Difficulty Retargeting Using DarkGravityWave

DarkGravityWave uses multiple exponential moving averages and a simple moving average to smoothly  adjust  the  difficulty.  This implementation  resolves  possible  exploits  in KimotoGravityWell  by  limiting  the  difficulty  retargeting  to  3  times  the  14  period EMA difficulty average.



Proof ­Of ­Work Utilizing X11

DarkCoin uses a new  chained hashing algorithm approach, with many new  scientific hashing algorithms  for  the  proof­-of-­work.  X11 consists of  blake,  bmw,  groestl, jh,  keccak,  skein,  luffa, cubehash, shavite, simd, and echo.

Because it is more complicated than a SHA­256 ASIC implementation, the use of X11 will prevent the use of ASIC miners for the short-­term to mid­-term future. It will also allow for a longer period of mining for CPU/GPU users.

GPU miners that mine with the X11 algorithm are currently experiencing reduced power usage (up to 50%) and reduced heat generation compared to scrypt.

[child_harold]

Lately it has dawned on me that bitcoin could become a tool for control in some dystopian future, and not the brave new technology to free us from the tyranny of governments and central banks.

The open ledger, lack of fungibility and lack of anonymity in bitcoin point to a future in which private finances could become  an impossibility in a world where everybody's money is held in the clear and visible to all members of the network and governments.

Disturbing calls from some members of the bitcoin community for government regulation only prove that bitcoin is losing its way. Seeking validation from the very same institutions the bitcoin protocol was designed to flout only means it will ultimately be co-opted by those same institutions, any vestiges of its former glory stripped away. Government regulation is anathema to the cypherpunks and to the spirit in which Satoshi created the bitcoin protocol.

Even if it were possible to add strong anonymity to bitcoin, the core developers are understandably nervous about adding features to a currency which is still seeking acceptance. Now that governments are getting involved it is a moot point. Adding anonymity to bitcoin simply will not be permitted by governments.

Pseudo-anonymity means nothing. You're anonymous or you're not. Pseudo-anaonymity is a broken promise, a crumbling cookie. Thus bitcoin falls short of its ambition to become digital cash.

Hence… DarkCoin.

DarkCoin is what bitcoin was meant to be. "DarkCoin is digital cash."

Darkcoin is the spirit of Satoshi and belongs in his vault.

I'd like to thank eduffield and the other developers for this vitally important evolution in crypto-currency.

Darkness hides things and some things are not for the seeing. Anonymity and darkness share this quality. Some people fear anonymity. To them it brings lawlessness,  zero accountability and anarchy. These people are ants.
 
We are grasshoppers.

Nxt is a second generation crypto-currency: a safe, transparent, decentralized system for sharing data and payments with people all over the world… and it’s so lightweight that all of its functionality can be accessed through a web browser.

It’s 100% Proof of Stake system, so you don’t need high-performance computing capacity to help support the network. Even inexpensive devices like smartphones can be used.

Nxt users are rewarded in exchange for supporting the network. All transactions in Nxt are bundled into units known as “blocks”. The more Nxt you have in your account, the more often you will generate a block and be rewarded with a fee.

The system generates a block, on average, every 60 seconds.
Every block contains: information on the transactions in the block,
the total fee for those transactions, a Payload Hash, a digital signature, as well as information about the previous block. As blocks are added, they form a chain. Data storage is secure, and completely decentralized.

In addition to basic transactions, Nxt supports an alias system, as well as a system for storing small amounts of data on the blockchain. Nxt also supports a decentralized voting system, and the first functioning, fully-decentralized asset exchange system. All together, these next-generation features allow for the creation of any number of decentralized services on top of Nxt.

With Nxt, crypto-currency becomes a crypto-platform: a tool for the creation of a whole ecosystem of decentralized applications for users!
