A lot of people do not like much Proof of Stake (PoS) coins as quite a lot of these do not have a long lifespan and are generally considered a loss of time and money, however there are some coins that have endured the test of time. Some of these coins might be an interesting option to invest into by buying and making some profit from the staking and future increase in their value, below we have compiled a short list of some such coins with a bit more details about each one and a link to the announcement thread on Bitcointalk where you can get additional information to help you make a decision. The focus of the list are coins with higher annual interest rate as if there is just 1% or less per year you can only hope to gain profit by long term increase of the value of the coin. When considering PoS coins that might be interesting for long term investment you should look for ones with higher interest rate that start at about 5% annually, but be careful with ones that have a very high interest rate as that might not be that good. Other things to look for include an active and bigger community of users, the coin being traded on larger altcoin exchanges such as Bitttrex or Poloniex with a decent volume. Check our list below with some such coins that we consider that are worth checking out in more detail if you are interested in making investment in Proof of Stake coins, the list may be missing some coins, so feel free to point additional ones in the comments below…

One of the main issues for users that are into altcoins are coins switching to PoS (Proof of Stake) or supporting both PoW (Proof of Work) and PoS (Proof of Stake) is that they need to run multiple wallets all the time usually with very low interest rate to keep them motivated. Of course the idea of PoS is to keep the network operational and with multiple nodes by stimulating users with rewards to keep their wallets running all the time, but this rarely happens as planned. This is precisely why the user interest usually drops in coins once they go to PoS pretty quick, but there is an interesting solution that might help users not loose interest in PoS coins and avoid the inconvenience of running multiple coin wallets all the time. Staisybit is an online wallet for multiple crypto coins that allows users to keep their coins stored in it and have them staked, earning rewards based on the interest rate that each coin has with very low fees. This will save you the trouble of running multiple wallets that can be heavy on the computer they are installed and require a lot of resources, especially if they are more than just a few coins. The drawback will be a smaller number of users running the wallet and supporting the network of the specific coins as the service runs a single wallet per coin with multiple users, but then again it is also about the convenience of the users.


Staisybit has been available for a while apparently, but it is not very well known among users apparently and is not very popular, even though it provides interesting service and is easy to use and works well. Currently the service has support for 13 different coins with PoS, they are: Bitz (BITZ), Blackcoin (BLK), Diamond (DMD), Energycoin (ENRG), Europecoin (ERC), Fuelcoin (FUEL), Noblecoin (NOBL), OKCash (OK), Shadowcoin (SDC), Sterlingcoin (SLG), Vericoin (VRC), CoinMagi (XMG) and Quotient (XQN). Once you register (set a secure password with small and big caps and numbers) you need to Open Wallet for the supported coin you like and send in some coins in order for the staking to start. The service can use a bit of polishing and needs some more information and details such as info on all supported coins as some of them might not be familiar to many users etc, but is still quite good and might be useful to some users.

BlackCoin (BLK) is pure Proof of Stake coin, except stage of initial distribution, when it’s mixed PoW and PoS coin. Recent Bitcoin patches against transaction malleability are integrated. Problem is not solved, but harder to exploit. Mining of Blackcoin will only be available for one week, since after the 10.000th block it will be a Proof of Stake coin only.
