I have looked at Decred but never got in only because I was staking a few other coins at that time but I might be able to start staking this coin now. I'm in the process of upgrading some hardware so that I can start sprouting Bean Cash again as that wallet uses a lot of memory. I'm also looking at a coin I had a couple of years ago and that is Reddcoin but this wallet also uses a lot of memory when staking so I need to weight up my options and see which is best for me.
If you want to reduce memory consumption, then simply use the "dbcache" and "maxconnections" command when launching your wallet via the command line (Windows) or terminal (Linux). Both dbcache and maxconnections can be set to the lowest value possible (for example: 4 for dbcache and 2 for maxconnections). At the cost of slower Blockchain synchronization speeds, your wallet will take up less memory from your system.
For example, if your wallet executable file is named "monetaryunit-qt.exe" then you would run the command as follows:
On Windows:
monetaryunit-qt.exe -dbcache=4 -maxconnections=2
On Linux:
./monetaryunit-qt -dbcache=4 -maxconnections=2
Where it says "monetaryunit-qt" you'd simply replace it with the name of your cryptocurrency's wallet executable file. Try it and see if it works for you.
As for Decred, it's an interesting cryptocurrency that's too hard to ignore. Of course, to earn some decent income with it, you would need to invest a hefty sum of money (as with most PoS coins). But, the results are outstanding. I'm currently staking Bean Cash, Decred, and Blackcoin. From top to bottom, Bean Cash is the most profitable, followed by Decred and lastly Blackcoin.
Take your time to explore the various PoS coins available on the market today, as you'll discover some unique ones from others. I've been looking into Diamond recently, since it's a PoS coin with a very limited supply that also provides masternodes. It's been quite undervalued considering that there will only be a maximum of 4.38 million coins (lesser than Bitcoin) in circulation. Not to mention, its masternodes are highly rewarding.
Not all POS coins have a high inflation rate, it doesnt have to be any greater then the general cost of POW and new issuance there. Are people staking with ETH now, I've been waiting for that to be a thing for too long
That's certainly true, mate. Some PoS coins have a low inflation rate, in order to prevent a massive decline in price over the long term. Peercoin is a good example of such PoS coin with a 1% annual stake rate. While it's not much, it helps the cryptocurrency maintain its value over time. Hyper-inflated cryptocurrencies like LiteDoge and Mintcoin provide big rewards to its hodlers but their value decays over time. Which is why, I believe that PoS coins with low inflation rates, will survive for a very long time.
As for ETH, I've also been waiting for its next big upgrade. Implementing PoS is taking a long time, as developers delay the upgrade every time. I hope that by 2020, we'd get to experience the new PoS Ethereum, as it will greatly benefit its price across the crypto market. In the meantime, it's just a matter of buying and hodling lots of ETH before it becomes a full PoS coin.
Once Ethereum is PoS, then there will be FOMO among people within the mainstream world. Hence, it could become one of the most profitable PoS coins in the future.
Could only be done by a pool which kinda loses the majority of the benefits to distributed networks a POS has over POW
Exactly. The PoS model of ETH will greatly benefit pools in the same way PoW is doing now. This greatly counteracts decentralization, as only wealthy people will be able to support the Blockchain and earn rewards from it. I hope that Vitalik would take decentralization in mind by reducing the number of ETH required for staking. If this happens, then many more people will join Ethereum causing greater demand and higher prices across the crypto market.
Nonetheless, I look forward to Ethereum's PoS consensus, as well as, the launch of a new staking pool called "Rocket Pool". Exciting things are yet to come for ETH, and PoS-based cryptocurrencies in general.
