Anybody else having problems with Cryptsy?

one of the best features so far!

Dang I am new here and love this coin. Might be new here but I was running a bbs back in 85 on my trs-80 coco 2 not sure what that has to do with anything but it sounded good. Anyway I think this coin has great potential. I have only been in the mining scene for about a month now I started with litecoin and than discovered Cry.

I agree about the peer review. I was following Mindfox's progress on the XBC wallet last month and I noticed that he took very serious the extensive testing of the wallet in different scenario's real time / sped up time although everybody was pushing him to finalize the release.

Also, his logic in discussions was always impeccable without showing ego or over(e)st(im)ating his own abilities. A remarkable person he seems.

@zeca, your enthusiasm is appreciated but the translations not always understood by me at least : )  Have fun here!

My post has nothing to do with DRK or XC. I do not own them and never did own them. I don't even know what XC is.

I'm just worried that these new features haven't been well thought-out. And you also can't have any serious privacy related product if it is not peer-reviewed by others - especially by people who specialize in cryptography and computer security.

I've seen too many crypto C++ projects that use crappy source code, sorry. This includes the code for original Bitcoin client. I can't say anything about source code for CryptCoin.

I totally agree!

I've stopped reading newbie/low post count accounts.

The quality of the posts are shit and they are just here to stir up shit.  Probably large drk holders.  XC crowd is much different and I have way more respect for them.

Who are all of these people with fresh bitcointalk accounts spreading doubt on our thread? Ohh, I get it.... They just happened to get into BTC last week, made a forum account and then came straight to our thread to tell us that CRYPT is not going to deliver? Very suspicious...  Especially since we are about to rival DRK and XC among others. 

What do you guys think of this?

Security analysis of CryptCoin's CryptCast feature

SUMMARY CryptCoin with CryptCast probably provides no more security than Bitcoin. CryptCoin users are advised to NOT ASSUME that their transactions will be more "private" (or "secure" in any sense) than regular Bitcoin transactions. Using CryptCoin instead of Bitcoin may in fact reveal more information about parties that are involved in transactions.

1. This document describes some potential security vulnerabilities in CryptCoin's CryptCast feature.
This feature is described in this document:
http://cryptco.org/Cryptcoin-CryptCast-Anonymous-Whitepaper.pdf

2. Simplifed example of CryptCast algorithm:

• Wallet A wants to send coins to Wallet B,
• Wallet A must somehow find the public key of Wallet B (this may be published on website, for example),
• Wallet A sends encrypted message to Wallet B: "I want to send you 10 coins in 3 transactions."
• Wallet B sends back encrypted message to Wallet A: "Ok, send them to ADDRESS1, ADDRESS2 and ADDRESS3."
• Wallet A sends 10 coins to addresses ADDRESS1, ADDRESS2 and ADDRESS3 in three separate transactions.

3. When Wallet A sends coins to Wallet B, these are just regular transactions that are visible in blockchain. The coins are not even "mixed" with coins from other transactions (CoinJoin concept).
So these transactions can be easily analysed with the same methods that can be used on Bitcoin blockchain. In fact it is probably even easier to do this kind of analysis because of smaller number of users/transactions.

4. When Wallet A wants to send coins to Wallet B, it must know only it's public key. With this public key it can request some new addresses from Wallet B.
In this case the third party has no direct access to these newly generated addresses.
However, this is also true when paying with Bitcoins: - user goes to merchant's website via HTTPS, - clicking button "buy now" which generates new address (in fact, it could generate multiple addresses), - user uses its wallet to send coins to these newly generated addresses.
So CryptCast does nothing else that Bitcoin is already doing today.

5. CryptCast's secure transactions are optional.
Secure transactions don't work if the computer of receiving party is not running a wallet (or is not online etc.). If the wallet is not running, then nobody can use secure transactions to send coins to this wallet.
However, this makes system very unsecure. If user of Wallet A uses secure transaction to send coins to Wallet B, it cannot "force" the user of Wallet B to use secure transaction when sending coins to Wallet C.
If the Wallet B sends coins to Wallet C using nonsecure transactions, this can make blockchain analysis much easier and the party that owns Wallet A can be much easier identified. In this case the analysis of blockchain is not "harder" than in the case of Bitcoin.
Nonsecure transactions usually use different "inputs" and they send them to one or more outputs. This automatically "proves" that the all these inputs belong to the same party (because there is no "mixing" involved at all). This effectively "nullifies" effect of secure transaction that was used to send coins from Wallet A to Wallet B.

6. When wallets are online, they respond to requests for secure transactions. This allows attack which can relate most wallet public keys with their IP address.
See this Coindesk article for short description of attack on Bitcoin network: http://www.coindesk.com/eavesdropping-attack-can-unmask-60-bitcoin-clients/
The similar attack can be used to reveal IP addresses that correspond to "public keys" of targeted wallets.
Such attack on CryptCoin network could be done almost trivially because of smaller number of nodes and because wallets must be online all the time to be able to accept secure transactions.

Very good..is gud coin..will go far probably btc-e one day.

I wanted to mention that no matter how bad talk!
I believe in this coin!

What kind of shipping does fud use now a days?  Fedex?

As for the others I do not know ...
But I'm trusting my 40-odd thousand of this coin in a odds of lifestyle, not just mine, most of all people deserve a odds in life!
I believe that no matter how fud shipping!
Ai is the message of a sincere supporter!
Luck to all!

Is there any features ready?

I bought 170 CRYPT coins this morning at 81000 satoshis, and I have a Buy order in at Cryptsy for another 665 coins if the price dips to 75000 satoshis.  Shoulda just bought them this morning at 90000 satoshis and been done with it.  And I have all my GPUs mining in dedicatedpool now also, right around 17-20 Mhash worth on the modified X11 code.

So make the price dip tonight to fill my order, then blast the price sky high using any means necessary!

Brillant Job guys!

I made very nice profits today

I mined at Launch and back now sorry but i was lost following shits :/ ehehe

Well Done!!

new wave coming soon

Well that was a fun ride.

Very true if your criticism is based on something, not just:  this anon wont work because it sucks and the whitepaper sucks..bla bla bla.  If it has some sustenance then great, if not then its just fud and will be called out.
