I hit a block after mining it for many days
tried to 'mint zerocoin', and 'spend zerocoin'
but the tx after 'spend zerocoin' sent to myself 1 zcoin never get confirmed by the network
ideas please ?

Zerocoin spends are larger than regular transactions and don't get picked up as fast. Currently I think it's limited to 1 spend per block for pool performance reasons (devs want to upgrade that later I think). So the transaction will get confirmed, even if not right in the next block but a couple ones later.

Ask ocminer for details as he's the operator of the Suprnova pool which currently mines pretty much all blocks. Cheesy

Last time, my withdrawal from Bittrex, took about 14 hours to confirm.
I thought the wallet had a problem, so, for now, i leave them all in exchanges.

I only let some -fast use- coins in the exchanges to be able to sell/buy quick.
Around 10%

The other coins are in my wallet.

I have got a bad feeling lo leave a big amount (if i had) there.
Too may "inside" hackers out there.

Good luck!

interesting.. didn't realise the first 280 blocks were scrypt-n, old school..
one of the neatest algorithm swaps i've seen; and all in one clean commit!

Amounts are shown, but the trick is that minting/spending happens in standardized denominations: 1, 10, 25, 50 or 100. This means deanonymizing you via transaction amounts is impossible because everyone uses these exact denominations in the crucial mint/spend steps.

A cheap trick i must say... Cheesy

H/s is decreasing.......getting really tough to mine....plus price isn't helping either

I've got 1,560 8-cores on it atm.

That's a lot of cores

Profitable at current prices?

Insanely, for me. And this time, I'm not even using a special miner. Well, I bumped it ~5%, but that's about it. The trick is cheap compute, this time.

Cool

Do you see future in this tech or just mining for profit?

Just mining for profit, here.

Price should alredy be at 0.03 now, considering that after zcash launch zcoin will be forgotten.

zcash future are 0.24 each (120 usd each zcash).

Zcash is an LLC registered in the US, which unfortunately very much makes it vulnerable to pressure from FBI and other suits (in fact they could be subpoenad by the NSA just like Lavabit), and it has the toxic waste problem. Zcoin is... I don't know what it is, apparently no registered company at all, and it uses the RSA-2048 number for its crypto setup (as you can see right here), which has been publicly available for 25 years and means there is no possibility of toxic waste in the developers' hands.

Also the Zerocash protocol hides all amounts, which in theory allows an adversary to use an exploit to generate currency while remaining undetected forever, while in Zcoin amounts are public yet transactions are still private, as explained in my other post above.

In essence, Zcoin has its strengths exactly where Zcash has its weaknesses. Not saying Zcash sucks, it certainly is a cool project with an amazing dev team. But to think that Zcoin has no reason to exist when Zcash is out is just foolish.

I heard many people talking about this coin in this forum. What is the difference between this coin and other anon coins?
I am just a layman and don't understand all the technical jargons. If anyone can explain to me, I can decide for myself whether this coin is worth buying.

It's the first cryptocurrency to implement zero-knowledge proofs, based on the Zerocoin protocol by Matthew Green, which allows a coin's history to be completely erased.

Making private transaction with Zcoin involves a three-step process:

1. "Mint" your Zcoin (XZC) into zerocoin (kind of comparable to a tumbler, except you don't need an external service and it's cryptographically secure with zero knowledge)
2. "Spend", which turns the zerocoin back into XZC in a brand new address in your wallet
3. Make a regular transaction with that XZC just like you would with Bitcoin etc – it will come from the new address, which can't be traced back to you.

Amounts are shown, but the trick is that minting/spending happens in standardized denominations: 1, 10, 25, 50 or 100. This means deanonymizing you via transaction amounts is impossible because everyone uses these exact denominations in the crucial mint/spend steps.

I think that you must have alot of free high speed multi-cores computers so if would have a this soft for mining

Not free, just cheap.

I get the approx same speed with a i5 4 core and i7 8 core, so there must be a trick there that i don't know

Nope, memory-bound.

Why has it been trading on trex 5 days away from the official release?

So what happens on launch day? Exchanges seem to just pull the source and list it on their own discretion. What would make the release date any different from today or yesterday?

Its not the first time when exchanges list crapcoins or IOU before the actual launch.

"hey we launched, happy trading" <- is this the actual business model here?

You realize this is Zcoin (not zcash) right?

Overall, it looks like its not hmmm. Im referring to this article https://bitcoinmagazine.com/articles/zcash-creator-on-the-upcoming-zcash-launch-privacy-and-the-unfinished-internet-revolution-1472568389.

Am I right in assuming that theyre not affiliated with Zooko Wilcox?

Since this is NOT Zcash I assume they're not affiliated with Wilcox... kind of competing parties?
