@ripper234, “bitcoin silver” is a funny analogy I don't quite get. It's not fundamentally any different than bitcoin in any way. Scrypt vs sha256, short rounds, and a larger monetary base... that's all cosmetic. The last two are literally one-line changes, with very little practical effect. It's still bitcoin protocol, bitcoin scripting language, bitcoin generating curve, and a hash-derived proof of work. It's bitcoin through-and-through, except for a choice of hash function that makes it resistant to parallel implementation.
And why? Because a few people on this forum didn't like that parallel sha256 made mining unprofitable for those without means? Please don't forget that the role of the miner is to provide security to the network, not to make you rich. Those hoards of GPU, FPGA/ASIC mining rigs provide security far, far better than any CPU-based system could. That time traveller attack? It still exists in bitcoin, but thanks to parallel miners, exploiting it would set you back millions of $$. With these new CPU-friendly, security-hostile *coins, any reasonable botnet operator will be able to herd more hashing capacity than the entire legitimate network, far into the foreseeable future.
“Tenebrix/Fairbrix/Litecoin: Bitcoin, minus the security!”
There is a claim that Botnets aren't that big of a threat (e.g. on
Tenebrix FAQ). I don't know if it's true or not, time will tell.
The advantages of a CPU friendly network is that literally everyone can play. It's released in a control manner, so no "hidden" early adopters. You don't need to compile C++ or run linux to be an early adopter of LiteCoin - just download and run. When Bitcoin was first released, this was certainly not the case.
I'm not saying that LiteCoin > BitCoin ... again, time will tell.
Fact is, when I told my friends about Bitcoin, half a year ago, I told them "yeah, it's a crypto-currency you can mine at home ... in theory. In practice, don't try it, because you'll just burn your CPU for nothing. How to mine on a GPU? I don't know, it's too late, the hash power is huge already".
So there are people who feel Bitcoin is unfair in some sense. Those people might not feel this about an noob-friendly fair alt chain that doesn't have a ton of pre-mined coins. Or might not.
If the theory is correct, new comers will not feel the "early adopter envy" to such a degree as it was with Bitcoin, and LiteCoin can at least find its market, even if it won't dominate over Bitcoin. I don't have anything better to do with my CPU right now, so I'm trying it out. Perhaps I'll even buy a few when there is an exchange, we'll see.
Every coin I've seen so far wasn't a good candidate as "silver", each for its own reasons. I think NameCoin could have been, but was deliberately underdeveloped (still no GUI, I don't know how much time after release).
Understand, it's not "bitcoin vs the alts". It's "cryptocurrencies vs fiat", and everyone that invests in Bitcoin should invest some portion in alts, because they have some chance of out-growing bitcoin, at least relatively. Even if Bitcoin market cap is X1000 than LiteCoin in a year, perhaps if I invest a small amount of time & money today,
my money will grow by a factor of 1000, while Bitcoin might only grow by a factor of 10. I don't know the likelihood of this scenario, but I believe it's possible.
Sorry for the long post.
