I believe that Bitcoin will grow again and just need an upgradation. just need time to grow again, this is just a story, do not be too confident with this news, big investors will raise again bitcoin and we are just waiting for that moment.

Yes i know what you mean and real $USD gets converted to USDT so they can buy Bitcoins so these "big investors" can pump the price up
because with Joe six pack knowing that it once cost $55 in miner Tx fees just to send BTC they are not buying

The only part you're missing is that USDT are counterfeit and the scam has come under the spotlight but lets blame the Bitcoin price going
down on China, France or South Korea  because we would hate people to understand the slot machine is paying out in fake plastic tokens
and no one will cash them up.

Just because of recent drop you cannot say that bitcoin is dead. Just think about it, btc came all the way from 1usd to 20K which meand 20.000 times more and then it dropped to 9k, it is still 9000 times more.

Yes and i think Tulips did this too but they never started of at $0.02 like Bitcoin stayed at for years so that 180,000 "times more"
503  Economy / Speculation / Re: this is the time to buy bit coin on: February 03, 2018, 12:03:49 PM
"this is the time to buy bit coin"

But someone here told me to "Buy on the dip" when Bitcoin went down from $19k to $17K so
I am fresh out of money because I panic brought at $17,300 using a short term loan and now
the landlord is knocking the door.

Do you think i should pay the rent or pay the bank because I can see that your a financial wiz-kid ?
504  Economy / Speculation / Re: do you think bitcoin will go back to 6000? should i sell now? on: February 03, 2018, 11:58:38 AM
stay focused on your choice because there are so many people who just talk bitcoin prices will never go up again and make the market panic, so the price goes down and can buy a lot of bitcoin. it is a dirty trick.

No man you love it because you can "Buy on the dip" !

Now I know you already spent your load soaking up cheap coins when the price went down to $17,000
so you should be at work now earning more money so you can keep "Investing"

I can see you on the beach now with two nice looking girls looking after you when Bitcoin hits
$100,000 but because of mining and CPU-Wars you cannot see the sun because all the pollution
has blocked out the sunlight but it's a price worth paying I say  Cheesy
505  Economy / Speculation / Re: do you think bitcoin will go back to 6000? should i sell now? on: February 03, 2018, 11:50:02 AM
bitcoin will never ever go up again
the reasons are:

1. technologically outdated, there are better and faster tech basis available, why by bitcoin when its price rise nimbus and hype is gone, and its tech is outdated? do people still buy iphone 1s or old mobile phone?
2. still high costs.
3. slow.
3. propagandistic competition, there are more than 1500 coins now, that challenge communist rule via central banks, the original small bitcoin community is gone an entire new decentral financial market is now in existance

and those holding the altcoins dont have reasons to talk good about bitcoin

Well said but you also need to mention that the cat is out the bag about the Lightning network being
a system of banks and that USDT might all be fake money and its been used to pump Bitcoin
506  Bitcoin / Bitcoin Discussion / Re: BTC UPDATE on: February 02, 2018, 12:37:40 PM
Took less than a minute to eat it all

Nom nom!

Sod your charts, history says this is going to $2K or less. Being saying this since the end of December.

It would had gone to about $50,000 but the miners put fees up to $55 and killed the golden goose
and now they are trying to blame India , France , South Korea and everyone else but shussh, don't mention
USDT turning out to be fake, backed by nothing

Well said that man

Not how the general views of people here not running big adverts in all the footer of their comments seem to
be at adds with none vested interest posters here !
507  Bitcoin / Bitcoin Discussion / Re: BTC UPDATE on: February 02, 2018, 12:34:40 PM
Maybe you need to factor in to you calculations

1. No one trusts the miners or development team since fees hit $55 and want out
2. USDT is fake money used to pump BTC and other coins and it might be coming to an end
3. Bitcoin won't scale and the Lightning Network is a system of hub banks

Head and shoulders, not many hammers and the tulip curve could well be what your seen
and yes i mad the last one up so don't worry  Cheesy

I just hope your statement will be read by a lot of bitcoin holders that is having a great panic since the price goes lower than $9K. They are like dogs who barks at someone they do not know but be gentle and playful once their owner comes in.

Steady the boat, stand your ground boys because this one has no clothes on and was saying "Buy on the dip"
when BTC was at $18,550 and will be saying just the same as he says above when it goes below seven.

The term your looking for is a foolish dog who barks at a flying bird (Bob Marley 1974)

509  Economy / Speculation / Re: Keep calm, and take a coffee. A trader said... on: February 02, 2018, 10:49:21 AM
I just love the smell of fear and panic in the mornings.

your comments are wasted here because if you tell slot machine players to go short they think
it's trader slang for saying get down on all fours.

How do you preserve profit when it's becoming clear that USDT is backed by nothing and fees
are still much too high for moving BTC thanks to the greedy miners
510  Bitcoin / Bitcoin Discussion / Re: Bad news dont hurt us on: February 02, 2018, 10:42:54 AM
Bitcoin with the lightning network has become a system of banking and fees hitting $55 has rubbed
off on every other coins too but the real reason it's crashing is because USDT was printing fake coins
and they were being used to pump Bitcoin up.

The "Bad News" keeps piling up but i find that if you close your eyes then you don't have to see it

511  Bitcoin / Bitcoin Discussion / Re: It's just feeling worse on: February 02, 2018, 10:22:34 AM
The value is now even below 9000$ and that's something close to what it was a year before

Absolute nonsense!

That is a very obvious lie!

The very first time that bitcoins was EVER above $9000 was November 26.  That is ONLY a few days more than 2 months ago!

A year before today, bitcoin was LESS THAN $980!


Yes and fees never went even close to $0.10 and then they peeked at $55 not long ago !

And the wheels were not falling off because the design of the network was useless when i came to scaling
512  Bitcoin / Bitcoin Discussion / Re: It's just feeling worse on: February 02, 2018, 10:15:27 AM
When i started bitcoin it was on $1200 and not same as what it was today. Though i lose a lot on trading because of red days, i still believe bitcoin will rise soon. Today's price is really somewhat intriguing but nothing to worry about. Bitcoin will rise again.

Yep hang in mate, you can go down with the ship and excuse others for heading for the life boats.

Bitcoin cannot last against the competition because we now have much better technology that will
scale and do 25,000MPH instead of 7 transactions per second but look at the good side, you will freeze
to death because these waters are too cold for sharks  
513  Bitcoin / Bitcoin Discussion / Re: It's just feeling worse on: February 02, 2018, 10:07:25 AM
The real reason it's crashing is because USDT is fake money and its been feed into the slot machines and
miners got too greedy and pumped fees as high as $55 plus more educated individuals can see that
the lightning network is a system of banking hubs and if the block chain was so good then why would
we now want everything off block.

During Prohibition they price of booze went up each time the government tried to stop it and next week
Taiwan will raid a miners house and they will be blaming the price drop on that

Your being feed propaganda about whats sending the price down and they are trying to pin the blame
on anyone else they can.

Prohibition sent the price of booze up, not downwards  
515  Bitcoin / Bitcoin Discussion / Re: protect investors on: February 02, 2018, 09:34:58 AM
I personally am afraid that the government with its regulation of the cryptocurrency can only make it worse. There is already a community, the ecosystem in which the regulators/banks want to enter and impose its laws. I do not say that it will be very bad, but the result may be different, including not very good for us all.
You forget that the Lightning Network has been designed to allow banks to operate and they are being ran by miners who have the
hardware and the BTC.

I won't be too upset if/when Bitcoin hits the floor and in any case it's more to do with USDT being fake than government
regulations and mega high transaction fees that crashing the price
516  Economy / Speculation / Re: Fear not,bitcoin will rebounce on: February 02, 2018, 09:26:47 AM

Smart people buy when the price is low Smiley

Yes $1.00 per coin and it took Bitcoin years to make it that far

Come on friend the party is over, your drunk and its time to head home
517  Bitcoin / Development & Technical Discussion / Re: Bitcoin’s Public-Key Security Level on: February 01, 2018, 08:49:33 PM
Bitcoin is using RijndaelManaged AES-Encryption with a 32 byte key so that makes 256 bit encryption
but the key that gets send at the start of the AES packet are PublicKey.point.X + PublicKey.point.Y using 65 bytes
and are based on a 256 bit Secp256k1 key

I can see that the X,Y bytes are based on the private key using Secp256k1.G.Multiply(privateKeyBig)
so what do I need here to get PrivateKey.X and PrivateKey.Y to do private key encryption because I am
sure this must be possible.

Would be nice to also incorporate transactions in at this level by playing with VI
518  Bitcoin / Development & Technical Discussion / Re: Bitcoin’s Public-Key Security Level on: February 01, 2018, 02:06:53 PM
find a way to create a new valid script corresponding to the precedent hash.//////////

The best i can make out is something like this

string Msg="My transaction Text , input/outputs "
Hash=DoubleHash(Msg);
byte[]SendData=privateKey.Encrypt(Hash + " " + Msg);


On the Bitcoin node they must be using the public key to then decrypt "SendData" but I suspected that the public key
could only be used to encrypt data and it did not work both ways around with Secp256k1 and thought therefore something from the public key
was being send to the nodes that somehow got linked back to the double hash so maybe my test code trying to decrypt using the
public key was wrong.

Someone please tell me that encryption with private key can be decoded with the public key using Secp256k1 will you please

519  Bitcoin / Development & Technical Discussion / Re: Bitcoin’s Public-Key Security Level on: February 01, 2018, 01:24:52 PM
In bitcoin all keys are managed by ECDSA logic, and I would hope, that the code to create the signatures (also in the windows systems) use the private key.  Cheesy

Not quite sure what your laughing at so let the cat out the bag because I like a good joke

RSA does both public and private key encryption but maybe you didn't know about that  Cheesy
520  Bitcoin / Development & Technical Discussion / Re: Bitcoin’s Public-Key Security Level on: February 01, 2018, 12:48:59 PM
What do you think of P2WKH (160bit hash of pubkey) vs P2WSH (256bit hash of pubkey) security?

In P2WKH you have to re-built an unknow script, and if you want to unlock a P2WKH Tx, you have to found a sha256 collision with the lock script of this transaction.
To me, it is still very secure unless you break sha256 and then, find a way to create a new valid script corresponding to the precedent hash.

in the code I am looking at on windows the wrapper just uses
System.Security.Cryptography.SHA256 and does a double hash and I can see that the public key
gets used to to create a signature along with the double hash so how does this work ?

I just thought the hash was used as a checksum of the signature contents and don't quite understand whats going on in the code below.
Code:
 public BigInteger[] GenerateSignature(BigInteger privateKey, byte[] hash, BigInteger? k)
        {
            for(int i = 0; i < 100; i++)
            {
                if (k == null)
                {
                    byte[] kBytes = new byte[33];
                    rngCsp.GetBytes(kBytes);
                    kBytes[32] = 0;

                    k = new BigInteger(kBytes);
                }
                var z = hash.ToBigIntegerUnsigned(true);
                if (k.Value.IsZero || k >= Secp256k1.N) continue;
                var r = Secp256k1.G.Multiply(k.Value).X % Secp256k1.N;
                if (r.IsZero) continue;
                var ss = (z + r * privateKey);
                var s = (ss * (k.Value.ModInverse(Secp256k1.N))) % Secp256k1.N;
                if (s.IsZero) continue;

                return new BigInteger[] { r, s };
            }

            throw new Exception("Unable to generate signature");
        }


Somehow later the public key must be used to somehow validate the two bigints returned from this funtion
