Exchanges trade both in Bitcoin and BitcoinCash, and I've just learned from the paper that they form a tree with a common origin. Does it mean that if I owned Bitcoin before the Bitcoin-BitcoinCash split, I can now spend it on both chains?

Yes, they share a blockchain history until a certain point. If your Bitcoins were sent in a transaction belonging to a block prior to the split, you own both BCash and Bitcoin.

  Why do people call it BCash? Because it's part of a social engineering campaign to discredit Bitcoin Cash and to prevent people from learning about the idiocy of what Bitcoin is doing. https://medium.com/@jonaldfyookball/why-some-people-call-bitcoin-cash-bcash-this-will-be-shocking-to-new-readers-956558da12fb https://medium.com/@jonaldfyookball/why-some-people-call-bit...

    The "bcash" term is used to attack BCH. It makes many of the attackers (that are everywhere on social media) pretty easy to recognize. They attack BCH because it is the only Bitcoin still working to allow massive scaling. Dark forces captured BTC to stop it from becoming a real peer-to-peer electronic cash for the world's people. BCH is keeping that dream alive and the dark forces have been attacking BCH since before it existed.

      Amount of trolls/fake comments from BCash community is insane. BCash is just a shorthand for a pretty shady coin that it is.

        You got fooled by a slick marketing campaign. Around fork time, there was a coordinated push, including websites, subreddits, youtube videos (title of video by jimmy Song interviewing Roger Ver was first known use), and the censored 'bitcoin' forums all calling the fork 'bcash'. One week later, Samson Mow even did a guest column for Forbes magazine[a] mentioning the term. Adam Back later Chastised Cobra for not calling it bcash. The goal appeared to be two-fold: 1. Strip Bitcoin Cash of the name 2. Frame it as a scam, especially if we take back the name. a. https://fortune.com/2017/08/07/bitcoin-cash-bch-hard-fork-blockchain-usd-coinbase/ https://fortune.com/2017/08/07/bitcoin-cash-bch-hard-fork-bl... "The newly created Bitcoin Cash (BCH) is a rushed spinoff of Bitcoin (BTC), a clonecoin of which there have been many in Bitcoin’s past.

    Because it's deceptive to call it "Bitcoin" Cash, because it's not Bitcoin. It's confusing to people who want to buy real bitcoins.

Yep. The split was also a taxable event (income) according to the IRS.
- nipponese 7y ago
  Selling coins from the fork is the taxable event, not the folk itself.

    The IRS guidance appears to contradict you. https://www.nysscpa.org/news/publications/the-trusted-professional/article/irs-releases-cryptocurrency-guidance-on-dealing-with-hard-fork-101119 https://www.nysscpa.org/news/publications/the-trusted-profes... If that is really their position, it's absurd and untenable... so I'm sure we'll see further clarifications in the future. Like how are you supposed to deal with forks that you do not know about or perhaps could not possibly have had any way of knowing about? You can avoid uncertainty, however, by selling right away.

      Are you not American? Have you notified the IRS of every single Bitcoin fork and every fork of every fork?

Yes, your private key will give access to the same amount of bitcoin, bitcoin cash and bitcoin SV
- ddtaylor 7y ago
  They will give access to the same amount held in those addresses before the date they forked. Coins sent after the time of the fork exist in separate chains except in somewhat bizarre cases where "replay protection" was not used.

yes, but be aware, bcash is plagued with scammers, so as a precaution you should move your coins on bitcoin to another wallet before attempting to use a bcash wallet which could steal your bitcoin private keys.

 The "bcash" term is used to attack BCH. It makes many of the attackers (that are everywhere on social media) pretty easy to recognize. Dishonesty and personal attacks are their "bread and butter". They attack BCH because it is the only Bitcoin still working to allow massive scaling. Dark forces captured BTC to stop it from becoming a real peer-to-peer electronic cash for the world's people. BCH is keeping that dream alive and the dark forces opposed to financial freedom have been attacking BCH since before it existed. I am sure there are BTC and BCH wallets that can steal your private keys. Don't use a wallet from an unreliable source for any crypto.

 "Dark forces" like people commenting here with anonymous brand new created accounts, slandering people who were tirelessly supporting Bitcoin long before they ever heard of it? Come on.
