There are way too many coins created daily to keep track of them. What you need to know tho:
SHA256 = Bitcoin
Scrypt = Litecoin
PoS = NXT
Hybrid = BLK
The rest have introduced a ton of algorithms, like x11 with DRK (Darkcoin, aka Dash) ,a bunch of other ones with QRK (Quark). Those are in my view gimmicks, we don't need that much anyway. SHA256 is as safe as it gets.
A project worth checking out: Maidsafe, they are aiming for an actual decentralized internet.
Thanks mate!!
What about digi?
and could you elaborate a bit on NXT?
I saw someone in another thread talking positive about them...
