At the end of the day, the algo is gonna change very soon, ZCash is launching tomorrow so who knows where the market is heading. There is going to be a major hype around ZCash but which will be the one that is adopted by the masses?



I'm preparing pop corn Smiley

Zcoin could still take the inner turn by releasing some slick wallets etc.

But does not seem like dev team has their shit together.

Unfortunate.

Considering the fact that Roger Ver is invested in both of these coins I would think the best approach is to have one hand in two pies  Grin. I think there will be a future for both however there is trust issues with ZCash, its all dependent if people can trust the ZCash devs. ZCoin on  the other hand has a RSA setup however the Zcoin  mint  process takes ages to get onto the block chain it took me 12+ hours to be able to spend minted Zcoins.

Both coins have there issues its all dependent on which is most trusted while been practical in real world scenarios.

I don't even worry as much about the Zcash devs but more a hacker finding an exploit and keeping his method hidden while he secretly mints coins.

Is a zcoin price drop inevitable in the coming days? Only time will tell. I think it might be good to switch my spare CPUs over to Zcash and buy Zcoin if we do hit a valley in price.

Or I won't flinch and will just leave the CPUs here. Depends on how busy the day is  Roll Eyes

Why would you mine a coin as much hyped as ZCASH is...? The hype is so loud, everyone will start mining it as soon as it releases, so it could be the worst time to mine it. It is like buying a coin, which is being hyped hardest. To me, if something is being heavily hyped, there is no opportunity anymore. You should be there before the hype, not after... As with ZCash its impossible, its better to buy it when interest will be not so big and it will be temporarily dumped (I am sure it will).

All this is theory, of course, as every coin is different and many scenarios possible...

Would be interesting to watch this Smiley. We should have exchanged ZCoin to maize instead of potatos, so we have a lot of popcorn ready Smiley

4x8 cores should definitely be better, but real measurements are welcome Smiley

What is the best miner to use for CPU? Does a miner exist for Windows or is it only for Linux and do I have to compile the miner myself?

Kraken just sent out an email that Zcash trading will commence in the morning. With a supply of almost zero and this hype, we haven't seen anything quite like this. Here's a paste of the email text: http://pastebin.com/q7wr8Wv2

Here you get two windows miner:

The miner recompiled by felixbrucker shows H/s instead von Kh/s

I know there is a ton of hype, and probably thousands of workers laying in wait for release... I'm lining up my EC2 instances right now too though  Wink

The hype is half the fun! other half is cashing out

Zcash futures trading at 1 BTC per Zcash on bitmex. The second best thing in anonymity zcoin is trading at $3.5?? Something is not right. either ZCASH should be at $35 ot zcoin should be at $70.

it's a faked price, it will be lower on a proper exchange, mostly because there is no volume there

It is not a fake price. it is an indication of how high will be price be once zcash is on exchange. Daily volume is more than 500 BTC on bitmex. I think zcoin is way better to go long at this price. than zcash.

I guess investors are banking on the fomo when zcash is listed in exchange.

Zcash will probably be overpriced out the gate.  I wonder if XZC price will rise as the inflation % rate slows.  Hard to say

One of the reasons is that the devs are working on MTP algo change to replace it so little incentive to spend work and time on an algo that is about to change.

Looks like a lot of people mistakenly think that Zcoin is a "Zcash" fork which can't be further from the truth. I posted this elsewhere but thought it would be good to have it here as well:

Quote
Zcoin is NOT a fork of Zcash in anyway.

First of all Zerocoin is the tech, Zcoin is the coin, similarly to how Zerocash is the tech and, Zcash the coin.

Zcoin uses Zerocoin technology from the Zerocoin paper. http://spar.isi.jhu.edu/~mgreen/ZerocoinOakland.pdf
This is a very well peer reviewed paper.

Zcash uses Zerocash. http://zerocash-project.org/media/pdf/zerocash-extended-20140518.pdf

Although Zerocash is a development from Zerocoin meant to address certain perceived shortcomings of Zerocoin, they are not simple forks of each other and rely on different protocols.

Zerocash was meant to improve on Zerocoin on these issues:
a) Zerocoin still requires a basecoin to convert back before being allowed to spend. Zerocash has no more basecoin
b) Zerocash's proofs are much more efficient and smaller than Zerocoin's
c) Zerocoin uses fixed denominations to mint (1, 25, 50, 100) while Zerocash is not subject to such limitations
d) Greater anonymity with Zerocash since sender/receiver/amount are all obscured.

However Zerocoin's advantage over Zerocash are as follows:
a) While still retaining the basecoin and a lot of the Bitcoin core code, it is a lot easier to integrate to existing Bitcoin merchants/etc.
b) Although Zerocoin's proofs are larger and occupies more storage space, the computational requirements to generate a private transaction are many times faster. Zcash requires large amounts of RAM and minutes of computational time. Zerocoin requires seconds to use and is not memory intensive. Basically Zerocoin uses more storage space but is computationally much less intensive.
c) Parameter generation for both Zcoin and Zcash requires a trusted setup but Zcoin's parameters are arguably less controversial. (https://github.com/zcoinofficial/zcoin/wiki/Parameters-in-set-up-phase-for-Zerocoin-in-ZCoin)
d) Most importantly is that in Zcoin, total supply is still visible so if there's a flaw and someone is secretly creating coins for themselves, this can be much more easily detected. With Zcash, because everything is hidden, if a flaw is exploited, it may be almost impossible to detect!
e) Zerocoin's tech is more peer reviewed and better understood than Zcash's. Zcash's use of zero knowledge proofs uses ZK-Snarks which very few people understand. Even Zooko himself admits he doesn't understand it (https://www.youtube.com/watch?v=P6RLjcGVUnw&feature=youtu.be&t=17m30s). Note that Zerocoin's paper was only like 15 pages. Zcash's paper is more than 50 pages so Zcash's is considerably more complex which means more things that can go wrong. This is why Zcash had to spend so much money on multiple security companies auditing on its critical components and bugs (including some serious ones have been found). A security audit is also not fool proof as the DAO exposed and which is why Zcash also uses multiple companies to audit.

Zcash is pretty neat technology and I think is a very amazing innovation but I do think that Zerocoin has a role to play. Its anonymity is still amazingly good with a much larger traceability set than previous anonymity implementations (basically all the previous Zcoins minted), it can be much more readily used today with existing vendors/merchants and can be used in a wide variety of devices today.

Calling Zcoin a 'Zcash fork' is ignorant and shows a lack of understanding behind the large amount of work put into both these projects.
