Vinny Lingham, CEO of Civic, onJanuary 11, 2019, predicted that the cryptocurrency might fall below $3,000.

Lingam states that the marketwould either breakdown or breakout. Bitcoin is trying to decide which way togo, therefore would trade sideways until the crypto finds a breakout orbreakdown direction.

On Thursday, within just a fewminutes Bitcoin shed $250 out of $4000. Thevolatility pattern of the Bitcoin took a new turn. The gains that were made earlier got canceledout. The price movements of Altcoinsreacted intensely to the price drop of Bitcoin. Almost all the cryptocurrenciesin the top twenty list by market capitalization shed 11.3% on Friday.

Recent research has identifiedthat hackers are using methods to calculate the private keys ofcryptocurrencies. They make use of a unique cryptanalytic attack.

However, these attacks occur onlyin cases where the developers have not executed their codes properly or in situationsthat involve faulty hardware that functions with multi-signature. Thosenetworks that are properly implemented do not suffer these attacks.

It so happens that anytime acrypto holder is involved in a transaction, they create a cryptographic signature.They make use of Elliptic Curve Digital Signature Algorithm (ECDSA). A nonce isgenerated by the algorithm. Thisarbitrary number is to be used for just once. It is important for the softwareto sign up with a different nonce each time otherwise hackers will be able tocalculate the private key of the signers.

Hackers continually monitor theblockchain watching for repeated nonces. Thus, they will be able to extractmoney from compromised keys. Hackers will be able to calculate the keys fromsignatures that make use of different signatures, but similar nonce. In cases,where the nonces have similar strings in the beginning and end of thesignatures then the hackers can exploit it.

The digital signature nonce isdifferent from the nonce used in the cryptocurrency mining process. The chancesfor exploitation of nonce are more when the values are very shorter than itshould be.

Lattice is an advancedmathematical approach that can be used to crack the wallet addresses toidentify the private keys. Several cryptanalytic techniques make use of thelattice algorithms as a building block.

This need not set most of thecryptocurrency users into a world of worry, because, a hack is possible onlywhen there is a bug in the digital signature code. The security scheme will be secure for aslong as it is executed according to the protocol and documented methods.The amount of time and electricity required forthis process is too high to make it profitable for attackers.
