Cryptsy to become the next MtGox ?!?
JournalA lot of people use Cryptsy to exchange there alt coins and even to sell there BTC for USD (its new market available to user who verify there identity).




WE ARE NOT ACCUSING THEM OF NOTHING. 


WE ARE JUST WARNING PEOPLE TO NOT KEEP ALL THERE BALANCES IN THERE.




At the same time they offer you rebate on your BTC balance. If you keep 0.20 BTC in there site, you will get around
0.00000007 BTC every day.











That is very tempting to keep your BTC in there system, but at the same time its a little bit scary how many people will do it and how much BTC it will take for the admin to get greedy and declare hack on there exchange or just close the exchange..





ITS JUST A WARNING. WE DON`T ACCUSE THEM OF NOTHING. JUST KEEP YOUR BALANCE ON LOCAL WALLET AND KEEP ONLY TRADING VOLUME ON THERE EXCHANGE.



P.S. This article is writen on 11.12.2014

CryptCoin introduce CRYPTWALLET
News



Bitstamp "operation wallet" is compromised
SecurityThe new year has begun with bad news for Bitcoin users and fans. The world’s largest (after MtGox death) Bitcoin exchange, Bitstamp.net "hot wallet" was compromised.
The site is offline to prevent any more compromise and warned users to stop making deposits to any addresses it issued before 4 a.m. ET Monday.
Bitstamp Service Temporarily Suspended

We have reason to believe that one of Bitstamp’s operational wallets was compromised on January 4th, 2015.

As a security precaution against compromises Bitstamp only maintains a small fraction of customer bitcoins in online systems. Bitstamp maintains more than enough offline reserves to cover the compromised bitcoins.
IN THE MEANTIME, PLEASE DO NOT MAKE DEPOSITS TO PREVIOUSLY ISSUED BITCOIN DEPOSIT ADDRESSES. THEY CANNOT BE HONORED!
Customer deposits made prior to January 5th, 2015 9:00 UTC are fully covered by Bitstamp’s reserves. Deposits made to newly issued addresses provided after January 5th, 2015 9:00 UTC can be honored.
Bitstamp takes our security and soundness very seriously. In an excess of caution, we are suspending service as we continue to investigate. We will return to service and amend our security measures as appropriate.
Bitstamp Team







The company ceo and co-founder of Bitstamp has assured users that all their bitcoins in the cold storage are secure and not affected by the hack.
The operational wallet (also known as hot wallet) consists of a fraction of bitcoins, which are frequently bought and sold on the exchange. Most users keep their bitcoins in the cold storage, however when they sell or buy a bitcoin it may enter the hot wallet until the transaction has been completed.
The website further stated that it has more than necessary reserves to cover the amount of bitcoins in the compromised operational wallet. The company has not released any further details as to how it was hacked and how the hackers got access to the operational wallets for the moment.

A lot of speculation and rumours hit the forums, that there is no hack at all. It could be the problem whit the price drop of bitcoins and Bitstamp liquidity .

Promising new crypto currency Ethereum
JournalThere is a new crypto currency called Ethereum and it looks very promising and good looking.

Official announce date : January 23, 2014

There official website is
https://www.ethereum.org/

Current price (24.11.2015) is 0.00309122 BTC for 1 Ethereum.

Our prediction is that by 1 January 2016 the price will rise to 0.01 BTC for 1 Ethereum.

The coin is 100% absolutely ASIC free due to the memory growth built into the algorithm (that means you can only mine with GPU and CPU only).

After 13 month Ethereum will switch to POS.
What is Proof of Stake
NewsProof of Stake is the "same" as Proof of Work (click on the Proof of Work to read what it is).
With Proof of Stake the resource that`s compared is the amount of coins you hold, so in case some one is holding 1% of all the coins, he will mine 1% of the "Proof of Stake blocks".

A proof-of-stake system might provide increased protection from a malicious attack on the network.



Proof of stake is a method of securing the network. Through various means. It is a system that rewards the miners for securing the network. They do this by minting POS blocks. Pos blocks are similar to Pow or proof of work blocks. Except no power hungry mining is required to earn them. They secure the network in the same way as POW blocks and make 51% attacks very difficult. You would need to have a sufficient amount of the currency up to 51% as well as 51% of the hashpower to invalidate both the POS and POW blocks making a 51% attack very costly to the malicious person.
What is Proof of WORK (POW)
NewsA proof of work is a piece of data which is difficult (costly, time-consuming) to produce but easy for others to verify and which satisfies certain requirements. Producing a proof of work can be a random process with low probability so that a lot of trial and error is required on average before a valid proof of work is generated.
With Proof of Work, the probability of mining a block depends on the work done by the miner (e.g. CPU/GPU cycles spent checking hashes).
In case you mine at a pool, the pool give shares depending on how much power you submit to them and after finding a valid block, they divide that block to all the people who contribute to mining it (depending on how much shares they got).

What is 51% attack on crypto coin
News





What is often considered a very large flaw in the design of Bitcoin (and all other crypto coins) is that hypothetically, if a single entity contributed the majority of the network’s mining hashrate, they would have full control of the network and would be able to manipulate the public ledger (blockchain) at will.
