Bitcoin Forum

BIP91 is activated and top of the forum it says
Why do we have to trust transactions with 5+ more confirms and not 1?Is there a chance that i send some bitcoin at this moment and the bitcoins gets lost?
How long to wait till it's safe to do transactions?There are not much unconfirmed tx too https://blockchain.info/unconfirmed-transactions why people are not making transactions today

Avoid transactions using bitcoin as the BIP91 is underway. Yes, you are at a risk of losing your bitcoins transacted when the blockchain is undergoing some development. Or it might not be processed at all. I don't really know but just follow the directives. In bittrex, they have this reminder also: Bitcoin wallet disabled until after BIP-91 is settled. I don't know how long this will last, but let us just wait for an announcement that everything is done and it is already safe to transact with bitcoins.

When we can do BTC transactions? How long this will take? I saw btc going down like from 2800 to 2600

BIP91 requires miners to orphan blocks that do not signal BIP141. If a transaction you receive is confirmed in such a block, this confirmation will be undone when the block is orphaned, potentially allowing the transaction to be double-spent by the sender. This becomes increasingly unlikely the more confirmations the transaction has, but it is a still a risk you need to be aware of, hence the recommendation to wait for more confirmations than usual.

This risk only affect you if you are receiving coins, not sending them (though if you are sending coins, the person you are sending them to will wait longer before acknowledging your transaction).

(This is also what the warning displayed by Bitcoin Core about "unknown rules" is referring to, though it can only give a generic warning since it doesn't know specifically what the "unknown rules" are.)

Only the last part is correct. OP, you would do well to disregard anyone with an ad in their signature, as they're just getting paid to post on topics they may know nothing about.

So does that mean it's not safe to withdraw bitcoins from exchanges at this moment?if i withdraw bitcoin from exchange and tx got undone that i am not sure i can get back bitcoin from that exchange.How long till this BIP 91 issue is settled and everything gets back to normal?

I have a small amount on Poloniex that I wanted to withdraw before 1st of August so that it is under my control in case of any chain split and also so that I can include it in the next Byteball airdrop.
Now I'm wondering if it's safer to leave it on the exchange?

it is not 5+ more, it is 5 times more.
it means if you were running a full node for example and receiving transactions and accepting them with 1 confirmation, now it is best to wait 5.
if you were for any reason receiving large amounts for example, and waiting for 3 now it is best to wait for 15.
if you were running an SPV wallet and waiting for the suggested number of 6 now it is best to wait for 30

your bitcoin won't get lost. if the block is orphaned as Fox said the transaction becomes unconfirmed. the chances is that the same transaction will be included in another block which is on the main chain. but it may just go back to mempool and stay as "unconfirmed" so the sender can potentially double spend that.

i explained the numbers above.
also the number of unconfirmed transactions has been low like this for a while now because the spam attack has stopped.

i think a more correct term is confirmed on an "orphaned chain." because things are much more complicated than that. i am not 100% sure on the details but, miners do a lot of spy mining, so there may be a block that doesn't signal so it should be orphaned but because of spy mining and them not verifying the block they don't know it and build on top of it. it can become even a long chain and your transaction may very well be on the 2nd, 3rd, ... 5th block that is even signaling correctly but built on top of a rejected block hence a long orphaned chain.

Well ever since the conception of bitcoins, the most advisable thing to do before trusting or using the coins received is to wait for 6 confirmations on the tx so as to avoid the risk of double-spent transactions. In the current state of bitcoin undergoing development, the thing is miners are required to orphan blocks that don't signal BIP 141. If you receive such a confirmation, the system will simply "reject" the confirmation that doesn't signal BIP141 and accept those confirmations from a BIP 141 signalled block.

I think it's better to wait a little and not to make any transactions until the moment when the price stabilizes. It is better to make transactions only as a last resort when absolutely there are no means for existence.

The transaction will still exist, it will simply be unconfirmed again after having previously been confirmed. It will confirm again unless double-spent in the meantime, and in that respect is as (un)safe as any other unconfirmed transaction; you just need to treat transactions with a small number of confirmations as being potentially unconfirmed.

Note also that it's always been possible for blocks to be orphaned for a variety of reasons, resulting in previously confirmed transactions becoming unconfirmed; it's just that now there's a much greater risk of it happening due to miners doing it intentionally.

Until SegWit (BIP141) is activated in (I think) about a month.

It would be better if you withdraw your bitcoins from the exchange and store it in your desk top wallet.Its because if a hard fork happens and bitcoin splits into two chains,almost all exchanges would suspend the deposits and withdrawals for atleast 24 to 48 hours.Also,even if you keep your bitcoins in your wallet,don't do any transactions during august 1.If you follow these steps,then your bitcoins would be safe.

From what he posted he has made it clear he wanted to move his coins to somewhere safe but what he is asking in which I am sure a lot of people are facing the same thing including myself is "Is it safe to move now?" which is really the bone of contention because what I read on the forum was to avoid any transaction 12hours before August 1 and I am planning to move my  few coins but now, its another thing entirely.

So you mean i should wait 1 month to withdraw my coins from exchange to be safe or should i withdraw now to my offline wallet immediately?
UAHF is coming on august 1 and i want to hold coins all chains if bitcoin splits but some are suggesting to wait till BIP 91 settles which will take 1 month.What to do now?

If the exchanges allow you to withdraw your coins then you should move that you personal wallet where you hold the private key as it is the best thing you can do even if there is any disruption in the network,always take the safe route and i think by August one you should avoid doing any transactions until everything clears up.

Yes most of the exchanges are currently allowing bitcoin withdraw but not Bittrex. https://bittrex.com/Status
Why they have disabled their bitcoin wallet if there is little to no risk for bitcoin transaction at this time.What all does that mean?My bitcoins are not on bittrex but on different exchange which is allowing bitcoin withdraw at the moment and i want to be 100% sure the bitcoin will reach my offline wallet without any issue if i withdraw now?

We should as we have done always. Based on that recommendation since 5 confirmation are needed before trusting anyone, we have to use highest possible fees so 5 confirmations will be in a maximum of 15-35 minutes. I think we should be very careful when dealing with different exchanges, I am withdrawing everything I have there and waiting what will happen after August 1.

This is a smart move to withdraw your all fund in bitcoin to your wallet, because anything can happen in 1 august, so to be careful we should withdraw all our bitcoins from exchanging sites or any other investement sites.
Anyways, As you said, we should increase a bite bitcoin transactions fees for being fast to confirm.

Right now I don't think people should be hindered from using their bitcoins. Just remember to store them independently in your own private keys before august 1 though. Also, since BIP 91 has locked in and theymos has set a warning that we should wait atleast 5 confirmations on our transactions as there could be problems.

I have just done few bitcoin transactions today without any issue but block are being mined slowly right now and difference between two blocks is more than 20 minutes right now so we might have to wait for atleast 2 hours to get required 5 confirmation to consider it as safe. However we can wait for few more days till all things will settle down and segwit will be activated without problem.

Well but always remember you'll be losing a few satoshis on moving your coins around. Nothing bad is going to happe and if anything bad should happen you'll not be shielded from it on August 1 irrespective of your wallet unless the exchange decides to rob you off your coins which I sincerely doubt.

If possible, it is better to refuse transactions with bitcoin until all the difficulties that have arisen are resolved. This already has official warnings on the forum. Those who will do them, risk losing their digital money and will act at their own peril and risk.

Currently, I only hold a small amount of BTC in my Nicehash wallet (Mining earnings) and BitGo. I've also sold a small amount on Kraken and it's stored in Fiat currency. I guess I'm not facing any serious risk on 1st August

Making transactions when BIP91 lock is very risky, many people are just dwelling and many also exchange who have done disable to deposit service and withhdraw they have. So this is a way to avoid unwanted things. Storing bitcoin securely with offline wallet is a priority, we certainly do not want to lose the bitcoin we have.

You can withdraw now if you want. You just need to wait for more confirmations than you usually would, that's all.

Then you must withdraw your coins immediately. As far as I know, no exchanges have any plans to ever support any UAHF chain.

EDIT: Typo

Pretty useful this topic
I made some transaction now, and everything went well
Was thinking that it was too late to move the coins to a safe place.

That is not exactly what it says, it says that you need to wait for 5 times more confirmations than usual before trusting transactions, if you needed 6 confirmations before trusting a transaction then that means that you need to wait for 30 confirmations, so if possible avoid transactions at the moment to avoid any kind of issue with your coins.

I dont see any issues with transacting BTC besides waiting for 6 transactions. So people, I see again this old practice of spreading FUD for nothing. Actually, the whole purpose of these FUD posts is to increase post counts for sig campaigns.

People stop spreading FUD! BTC network works as usual.

i would avoid to move your coins at least for the first week near 1 august, i also wonder what will exchange do, if everyone start to get his coins to his wallet, and no activity is done anymore on the market


well if you are sending someone is receiving, and if he/she is affected than no one can make any transaction

Should we do Bitcoin transactions at this time? Please understand if the increase and decrease of bitcoin itself, if it is profitable can transaksikan your money to bitcoin.

yes is good, don't save your Bitcoin in the online wallet if you do not want risk to lose your bitcoin. Converting coins into fiat money is a great way to avoid risk.

It would be better to avoid bitcoin transactions since there is a fear of hard fork during august 1.Also,withdraw your bitcoins from exchanges and keep it in your wallet safely as most exchanges may suspend deposits and withdrawals for 48 hours as they did early during ethereum hard fork.

its better to waiting until everything works fine then you try to make transaction. i think its not a big problem for us to waiting for a while because we don't know what will happen if we are want to make withdraw or deposit. i think its not a problem if from 1 confirmations become 6 confirmations because our transaction in the end will be arrive in destination wallet, so don't be too worried for this. there is no need to be afraid and it is worth to be patience until there is any statement that if we want to make transaction is clear and its run properly.

I am not really bothered with the additional confirmations it would take for a transaction to get through, because as long as my transactions are successful, that wouldn't cause me to panic or make any unnecessary actions. I would just lessen my transaction count and wait out until the coast is clear. But right now, everything seems to be working the way it should, so I guess everybody should settle down and act accordingly.

Seems like the only problem is more confirmations.

If you're okay with waiting a bit longer, then that's fine.
But if you do not want to risk you bitcoin, then don't.
Just wait until everything get settled down.

Even i am completely not aware about bip91 how it change as far my iunderstanding block will be splitted to two and each will be 1 MB . So i already converted bitcoin to altcoins some into fiat currency.

There's already an update with BIP91. It is stable but it is a good thing that we are warned about possible loss of confirmations, if you are willing to take the risk transacting bitcoin, the blame must be on you on the possible lapses that might take place.

China is putting out fake news to drop the price and they will buy all the cheap coins. :D

We are not stupid this is obvious and I will also buy the cheap coins thanks to China. ;D

Yes why wouldn't you the network part is completely different from bitcoin price no matter how badly the price has fallen the network won't face any issues there are excess delays occuring nowadays but the speed is still decent on the fees has increased a bit otherwise everything seems fine

the event has now passed you transact bitcoin back. I think all the bitcoin wallet purses give a warning to bitcoin purse users not to make a transaction when the date starts. for fear of losing the bitcoin you have when you make a transaction. bitcoin has a segment and it will have an impact on your bitcoin. this forum has explained in every thread to be careful in storing bitcoin because of the consequence of this bitcoin you lost. therefore the moderators are calling on all bitcoin users to store bitcoins on their offline wallets. to keep your bitcoin safe. but the event is over and we are free to make transactions.
