Title: Are my bitcoins safe if I don't split them? Post by: CryptoEnthused on December 10, 2017, 08:50:35 PM I'm really concerned about my money. Can I send my bitcoins to anyone without risk of losing my bitcoins? As I understand If i send my bitcoins, then someone can claim only my bitcoin diamond?
Also, what happens if I send my bitcoin to my own another address, can some still steal my bitcoin diamond? I can't fully understand how replay attack works. Hope the community can help figure it out :) Title: Re: Are my bitcoins safe if I don't split them?

No, If you sent bitcoins out the bitcoin diamonds (and other forks) will stay on the original address ( but if you give him your privatekey then he can get all the coins on that wallet BTC, BTG , BCH... all of them) To sum up. PRIVATEKEY IS THE KEY TO YOUR COINS (all of them) ... so when privatekey is not compromised, you are safe. Title: Re: Are my bitcoins safe if I don't split them?

It's another BTC fork (same as bitcoin cash and bitcoin gold) ... search for more. Title: Re: Are my bitcoins safe if I don't split them?

Bitcoin cash for example changed blocksizes, bitcoin gold changed how bitcoins are mined (Equihash). http://www.btcd.io/ It looks like they want to improve, according to their website: Quote *Protection of privacy *Reducing the cost of transfer * Reducing the cost of participation https://i.gyazo.com/2a75db971d7a5dbdafc27f07472a672c.png Title: Re: Are my bitcoins safe if I don't split them?

Can you explain how this happens? I just heard, that if you don't split the coin, then when you send bitcoin, someone can steal your forked coins or something like that. I'm really confused about this part. How that replay attack happens exactly Title: Re: Are my bitcoins safe if I don't split them?

I'm really confused about this part. How that replay attack happens exactly Indeed, because the transaction signature and hash will be the same on both chains. Someone could then copy the signature + hash to spend the same amount on the other chain. Lets say you have Bitcoin X and Bitcoin Y. Bitcoin Y just forked so all the UTXO's on Bitcoin X are also present on Bitcoin Y. ( Bitcoin Y has no replay protection). You try to send 1 Bitcoin X to your exchange adress, that bitcoin X generates a valid hash + signature, ( for the transaction to confirm.). Now that hash + signature will also be valid on the Bitcoin Y chain, meaning that anyone could copy it, and sent/transact your Bitcoin Y. Note that the amount must be exactly the same ( otherwise the hash/signature would be invalid again.) There's some interesting answers on how to prevent them here - > https://bitcoin.stackexchange.com/questions/52210/what-is-the-best-way-to-prevent-replay-attacks-in-the-event-of-a-bitcoin-hard-fo/52260#52260 Title: Re: Are my bitcoins safe if I don't split them?

The best description I've seen so far. Very explicitly and short |
