can u let us noobs know all those differences are that makes securecoin so much better?
If you are new to the idea of crypto currencies, crypto commodities or however you want to call them, I recommend to begin with an evaluation of basic concepts.
Proof of Work (PoW) was introduced by Bitcoin and is used to secure the network and to verify the integrity of transactions.
There have been several attempts to introduce new algorithms for doing the PoW.
Litecoin was the first successful implementation of scrypt (Tenebrix was earlier but failed) to replace Bitcoin's SHA.
Lots of copy-cats followed.
Quarkcoin and Securecoin are examples of implementations that utilize a bunch of hashing algorithms and not only scrypt.
Primecoin is the first successful implementation of a completely different PoW that doesn't rely on creating hash values at all but on finding Cunningham Chains (which might create some data for number theorists - who knows... At least it is not as intrinsically useless as creating hashes).
And there are completely new approaches to secure a network without the need for tremendous amounts of mining devices running steadily to prevent from
> 50% attacks.
Proof of Stake (PoS) is such a concept which was introduced by
Peercoin. This is completely different from PoW (although Peercoin has PoW (the same like Bitcoin) as well; it is the PoW/PoS combo that makes Peercoin special).
Novacoin uses PoS, too. If you call Peercoin "Bitcoin + PoS", you might call Novacoin "Litecoin + PoS".
Meanwhile there have been lots of copy-cats for that PoS concept as well.
PoS secures the network and verifies the integrity of transactions not by energy consuming high-speed mining devices, but by the Peercoins themselves.
Explaining the whole process might lead too far. I recommend doing your own research. You might take this as a start
PoS might be one of the most revolutionary ideas about crypto coins since Bitcoin itself! Find out yourself...
It might not be possible to claim one coin "better" than another, because this rating is based on subjective evaluations. There is no absolute "good" or "bad" in this area.
You can try to rate them based on their concept.
Do they bring something new and useful?
Is that something that is likely to be integrated in the Bitcoin development or rather not because it conflicts with its basics?
Or you can try to estimate market adoption. Because a coin will not only succeed because it is good by design... But a good design might be better than a bad one. Once again: good/bad is up to you!
And you should try to find out whether you are more interested in investing or in speculation...
But for both investing and speculation I recommend not to spend money for things you don't understand and especially in the case of crypto coins/commodities: don't spend money you can't afford to lose!
It might be hard to succeed by speculation, because you bet against an agile market of well-informed people.
If you are heading for long-term investments, you might bet against lots of people who don't know about this all, yet, but might become interested in that stuff at some point of time in the future.
