Bitcoin Forum

As the title says everyone must get asap their coins from exchanges, startup that will not protect their platform or they dont care to protect their platform from the replay attack problem. 
The reason is that will be very easy for someone to attack this platform and drain all their bitcoin or forked coins. 
 
Until now Xapo seems to not care to protect their customers as the last blog post says.

Coinbase says that will split their coins and that  their platform will have a replay protection.

Bitfinex will have a replay protection and they will split their coins after the fork. For that reason they will halt withdraw, deposits to their platform for 24 hours maybe more.

Bitcoin.com will not care about replay protection and will be a great danger for everyone to keep any coins there. 
 
Until now is not clear what they will do big exchanges like Kraken, Bitstamp, Bitflyer and startups like Bitpay, Blockchain.info and is very danger to anyone to keep their Bitcoin there.

Regardless of the upcoming forks, it is generally better to avoid letting others hold your bitcoins for you.

It's not clear why you write that "Xapo seems to not care to protect their customers". According to Xapo link you posted:

Also, Blockchain.info doesn't hold your bitcoins for you. They belong in a discussion about which chains the various wallets are going to follow.

and is very clear that you didnt know what a replay attack is. You can reaplay attack the forked coins and drain bitcoins from their platform. The reason is very simple. Xapo will not split their coins after the fork.

I don't know about this replay attack but it seems important. Can you please explain it to me?

That will depend on how the platform manages their transactions.  There is no evidence that XAPO will handle it poorly.


FUD and NONSENSE.

There is nothing in XAPO's announcement that indicates that they will be vulnerable to a replay attack.

Do you even know how a replay attack works?  Do you have any evidence that XAPO is not taking proper precautions.

Please, go away troll.

to split your coins you need
1. hard fork to happens and
2. to transfer all of your bitcoins to the new addresses that is only spendable to the forked chain.
To do this an exchange or a payment provider with such a huge bitcoin asset it need hours maybe days.
Xapo will continue trading as nothing will happens. Is very clear that they will not add any protection against someone that malicious want to drain their bitcoins or forked coins from their platform.

This is not true.


This is also not true.

All the necessary work to protect against replay protection can be done before the split happens, while the system is still running.  It is quite possible that Xapo has completed all the necessary work months ago.


Trading has nothing to do with replay.  Trading happens entirely within their own system.  The only place they need to worry about replay protection is withdrawals.  They could halt withdrawals if they need to, but it is quite likely that they already have replay protection in place for withdrawals and therefore do not need to halt anything.

Furthermore, replay does not allow anyone to "drain their bitcoins or forked coins from their platform".  It only allows someone to take a transaction that occurs on one fork, and send that SAME transaction on the other fork.  While this would be bad, it doesn't mean that someone can suddenly drain all the cold storage.

what kind of replay protection they will had? Because as i say to protect their platform from someone to transfer to his wallet the same amount of bitcoin or forked coins is the exchange to split their coins AFTER the fork.  And this need time.
Even their cold storage to protected from a replay attack it must split after the fork.
I think you have not really understand what is a replay attack

how is not true? You don know what happen to Coinbase with etc-ethereum fork?

Wences Caesares couldn't care less about bitcoin, he is here to make dollars, just like everyone else involved in segwit2x. Just now, here is what segwit2x dev had to say about full nodes:

The anti-node agenda is real. They want to make bitcoin not sovereign, but subjected to their corporation's decisions. We MUST stop using any of these corporations for life, they are not to be trusted ever again. The only good thing they can do is going bankrupt.

The CEO of Xapo has a story of supporting big block forks. Can't trust it.

And as I say...

You are incorrect.


I don't think you understand what cold storage is.


I do understand.

Are you sure you do?

BCH spoilt people. They saw what happened to those who had coins in exchanges - 0.4 BTC and more per shitcoin.

There's still plenty of time between now and this supposed fork. I think the most likely scenario is that it won't happen at all. Second most likely is that it'll emerge as an alt with replay detection that'll die very rapidly.

It is not true, because you do not need to "transfer all of your bitcoins to the new addresses that is only spendable to the forked chain".  You simply need to include a single input in your transaction that exists on only one side of the fork.  If you do that, then the entire transaction cannot be replayed on the other side.

I can bet you that all the exchanges will stop deposit, withdraws for hours maybe for days to solve this problem. Exchanges or payment providers like Xapo that will not protect their customers will had a serious problem.

It's not a problem, because most exchanges have already solved it.


There is no reason to believe that Xapo will not perform replay protection.

Your FUD and NONSENSE is getting boring.

and in my view your denial for a danger situation is very danger. Is danger to say to a bitcoin holder to this platform that everything will be Ok in the same time this platform switch a chain without wanring users and the most danger switch a chain without a replay protection to their platform
I dont know what economical relationships you have with Xapo but i have to warn ppl about it.
Replay attack happen before two years in summer to Coinbase and had a result this exchange to lost thousand of  ethereum classic tokens. This attack can easily can be in exchanges or payment providers that not take measures to solve it like Xapo as i say.

That is a danger for ALL platforms.  If you don't have exclusive control of the private keys, then you don't have any bitcoins.  All you have is a promise.  This is true of Xapo, Coinbase, BitFinex, and all the other businesses that accept bitcoins and provide bitcoin denominated accounts.


Fortunately, Xapo has warned users about what they plans are for choosing and naming the chains.


And since you have no evidence that they won't have replay protection, you are spreading FUD and NONSENSE.


None at all.  I'm just pointing out the rediculousness of your claims so that others don't become frightened by your wild imagination.


You have the right to imagine and say whatever you want.  But I have the right to point out your ridiculousness to those that might read the nonsense that you write.


So, perhaps you should be warning everyone about Coinbase incompetence then? The fact that Coinbase had a replay problem in the past is not evidence that Xapo has a replay problem today. 


Unless Xapo has stated they have a replay problem, or unless you work for Xapo and are authorized to speak on their behalf, or unless you have actual evidence of a replay problem at Xapo, you are just making up nonsense out of your own imagination and then making baseless accusations.

Slander is an evil behavior and you really should be more careful about making false accusations.

“Do not judge, or you too will be judged. For in the same way you judge others, you will be judged, and with the measure you use, it will be measured to you.

Why do you look at the speck of sawdust in your brother’s eye and pay no attention to the plank in your own eye? How can you say to your brother, ‘Let me take the speck out of your eye,’ when all the time there is a plank in your own eye? You hypocrite, first take the plank out of your own eye, and then you will see clearly to remove the speck from your brother’s eye."

and how you call it if someone fork the chain and force ppl to follow their forked chain as Bitcoin? Why i have to trust this ppl and why you have to blame me as a slander when Xapo try to fraud ppl money.
And where they say that they will add a replay protection for their customers?

Capitalism.


I never said you have to trust anyone about anything.


Because you are saying false negative things about them.  That is slander.

Sounds to me like they are planning on protecting their customers.

Sounds to me like you are engaging in evil, lying, manipulative, slander and defamation to create FUD and scare people. A common description for such behavior is "troll".

Taking your crypto currencies out of your exchange wallets should never be just done because of an upcoming hardfork. Instead, you should always keep you possesions in your hard wallets and put cryptos on exchanges with amounts that are just right for your usage. Be paranoid and be safe.

ok in the future i will point you for everyone that will need help about money lost or misleading false cross chain trasnactions from Xapo platform. As i see you have get the role of Xapo defender and the role of their customer support.
You have not answer yet what is your economical relationship with them. Because and this is what i call capitalism. Only someone with economical relationship wil defend them with such a passion.

I have never trusted in any exchange, not even coinbase or blockchain wallet, i only store my bitcoins on an offline wallet, i am very happy with that, because i know that i have the full control of my coins and that nobody is going to steal them from me. It is too risky to store your coins on a exchange, and you all must know that from the beggining, a lot of exchanges close without previous information.

That's fine.

I've been here for 5 years helping people. I don't mind helping them in the future.


And you have get the role of Xapo slanderer and defamer. How much are you getting paid to do that?


Yes. I did. learn to read.



I'm not defending them. I'm just pointing out the ridiculousness of your thread to protect those that might not know better and might become misled by your nonsense.

can you stop offend ppl and to play the smart guy? I never offend you and never use term like you use even if you support with passion hoaxers and a fraud attemp from Xapo to swap customer coins from bitcoin to a new altcoin without any permission.
You support this payment provider and you are not warn ppl about the danger situation that they enter if they keep their bitcoin to this platform after the fork.
And you refuse to notice the danger situation with the replay attack, because this fork will have not any replay protection at all.
Who is misleading ppl now? Me or you?

and this link is for you or better for your beloved fraud startup...  ;D
