Topic: Wallets currently accepting Bitcoin Cash? (Read 236 times)

a replay attack only occurs when a transaction on one chain is also valid on the other chain. and since these forks are also copying the transaction history, the transaction output you are signing exists on both chains.

bitcoin and bitcoin-cash:
the method of signing is different since BCH has a different signhash byte so the signature hence the transaction that is valid on one chain is not valid on the other.
as a result you don't have to worry about anything. you can spend BCH first, or BTC first or simultaneously. it can not be replayed. the only thing to worry about is importing your key in a malicious software that can steal both coins from you.

bitcoin-cash and bitcoin-cash-sv!:
they never changed anything when they forked so a signature on BCH is valid on BSV so it can be replayed. as a result you have to manually split your coins which means first sending each coin to different addresses you control and if you succeeded then you can easily spend each token without worrying about replay attacks.

---

(for future references and future forks) an alternative way of protecting yourself against replay attacks for when you have no other option is this:
- it will be easier if one chain to be at least a little slower than the other.

1. create 2 different addresses.
2. create 2 different transactions spending the same transaction output(s) but sending to a different address created in step 1 (lets call then tx1 and tx2)
3. broadcast tx1 on chain1 and broadcast tx2 on chain 2. do it at the same time with least amount of delay. (automation can help a lot in this case)
4. wait for them to confirm.
4.1. if both transactions confirmed (tx1 on chain1 and tx2 on chain2) you have successfully split your coins so continue as you will.
4.2. if only one transaction confirms (tx1 on both chain1 and chain2 or tx2 on both chains) then go back to step 1 and repeat.

* i don't know hashrate of BCHSV but someone posted a picture once showing it has less blocks, so it may have lower hashrate and be slower. so it can work.
* step 2 works because nodes reject double spends. connecting to more nodes and broadcasting your tx to them makes it more likely to succeed.

I will check there now Pmalek.

There is a whole bunch of Bitcoin Cash wallets suggested on the official site by clicking on Wallets on the top of the page.

None of them are accepting BCH now?

Well said.

Forks are worth a significant percentage of anyone's holdings, and for now they are far too complicated and risky to be claimed.

 Like I said the Electron Cash method looks like the only way of safely splitting coins for now but you have to jump through quite a few hoops.

Thanks. I don't think I'll try it. For someone with only basic computer knowledge, it's very complicated . I think all this needs to be made a lot simpler before the general public get involved in bitcoin.

It's happening right now in certain places. You can transfer to Kraken now. I think Kraken also split them automatically for you. Not sure about other places. The issue is the possibility of losing coins on either chain sending the other which is why one needs to be careful until enough wallet providers offer a mechanism, then again if there isn't proper replay protection on either chain, of which there's no sign at present, they may not bother for a long time yet.

Thanks again. I appreciate each and every reply. Has anyone any idea when the transfer & selling of BCH & BSV will become possible again?

You are right. If you import your 12 words in Coinomi, Electrum, or whatever wallet, those private keys are going to be exposed. There is a small chance a bad actor will be able to steal your coins at that moment.

In your BTC addresses, you will have BTC, BCH ABC, BCH SV, among other less valuables forks such as BTG and BCD. All those forks are worth money, and depeding on the amount of BTC you have, they could be worth thousands of dollars.

As explained above by gentlemand, the best option for now would be to wait for some days/weeks until BCH fork drama ends. You are holding those coins for years, just wait a few more days to be safe.

---

However, there is one more option for you, that would be safe, but will require some work and knowledge: use an offline computer (airgapped).

If you have an old computer, disable it network in bios. Format it. Never plug it in the internet again, so there is no risk of being hacked.

Download https://iancoleman.io/bip39/ and upload it to your new airgapped computer.

You can safely enter your 12 words there, without any risk of being hacked, as long as the computer never touches the internet again.
Then, once you have entered your 12 words, just Scan the private keys QR codes with your Coinomi mobile wallet. Get all the forks you want (BTC, BCH ABC, BTG, BCP  whateever, coinomi supports lots of them). When BCH drama is over, try to recover the BCH SV (i think it's ok to claim bch abc now, but not to sell it).

These coins were present before the Bitcoin cash fork. So you're saying the BCH coins will still be in my paper wallet after I transfer the BTC out? The problem seems to be that I can't transfer the BCH out to sell somewhere as most exchanges seem to have suspended transfers & dealings in BCH since last week's hard fork, so when I move the BTC out, I will have exposed my private key & the BCH will no longer be secure. Please correct me if I'm wrong. Sorry if I'm asking questions which to many seem extremely basic but I have never done this before & want to be sure I get it right.

I'm not sure I understand the problem here. Bitcoin and Bitcoin Cash are now separate chains. If you create a transction to move your Bitcoin from one wallet to a new one, then the coins will be registered as spent on the old wallet. If the old coins were present before the Bitcoin cash fork, then they will still be available as Bitcoin Cash tokens on their chain, and, as there will no longer be any Bitcoin left to spend on that chain, you should be able to claim those without the risk of a replay.

Have I misunderstood the situation?

Thanks again I'm Android.

Are you android or iOS?

I use mycelium for Android even though it doesn't have segwit yet. Coinomi handles loads of different coins and I've used that without any trouble too.

Couldn't tell you anything about ios.

Any suggestions as to a decent phone wallet?

You're right about the private keys. What I do is use an Android device and use the Mycelium cold storage spending feature to sweep the private keys. Supposedly Mycelium instantly purges them from its memory. I don't know if that's true but I've never had a problem with it.

Even with that possibility of exposure, it's still potentially less messy than trying to transact BCH right now.

You can also use Electrum to sign a transaction offline so you won't have to expose the keys -  https://bitcointalksearch.org/topic/how-to-sweep-a-paper-wallet-into-an-electrum-wallet-using-a-cold-storage-setup-2261012

If you're sweeping a private key to a Bitcoin blockchain.com wallet the only thing it'll see will be the bitcoins. It can't talk to the BCH chain(s) because the transaction isn't taking place on that/those chains.

And I wouldn't recommend a blockchain.com wallet. It's only as safe as the device you're accessing it with which probably won't be safe. Any decent phone wallet will be more secure.

Anyway this is a guide to splitting the BCH if you're keen to do it now. I still have some but I'm not bothering for now - https://medium.com/@antsankov/how-to-safely-split-bch-and-bsv-coins-using-electron-cash-w-pictures-ba2d2935b4cc

Don't forget all the other forks too like Bitcoin Gold and lord knows how many others.

Thanks for your reply. I really appreciate any help as I really don't have a clue what I'm doing & help seems to be limited! I don't actually want to do anything with my BCH but once I move the BTC out of my paper wallet surely my private keys will have been exposed to the internet & I'm at a greater risk of having the BCH stolen? I know they're not worth much at the minute but every little helps!

Can I just ask as well - when I go to transfer my BTC to Blockchain.com, will it automatically know it's the BTC I'm moving & just leave the BCH untouched?

This would be a genuinely awful time to attempt to do anything with the various Bcashes. Electrum won't have anything to do with it. There's a ripoff called Electron Cash that I think also allows you to choose between the two chains by selecting the relevant server but there's still a possibility of losing coins on the other chain.

Are you in any hurry? If not then I'd wait. Just move the Bitcoin and wait for wallets to sort out the BCH.

I am moving some of my BTC from my paper wallet to my Blockchain wallet to sell. That paper wallet presumably also contains the Bitcoin Cash I was given last year. Can anyone tell me which wallets are accepting Bitcoin Cash at the minute?.....Electrum doesn't seem to be nor Blockchain - everything seems to have been put on hold since the hard fork in BCH.
