Here’s a summary:
In Coinbase’s 24 Oct post, they planned to refer to the current and new bitcoin blockchains after the SegWit2x fork like so:
- The current Bitcoin will be known as Bitcoin (BTC)
- The forked blockchain will be known as Bitcoin2x (B2X)
In their latest 25 Oct post, they indicated that they plan to “call the chain with the most accumulated difficulty Bitcoin.”
This means that the forked 2X could possibly end up as BTC on Coinbase. They haven’t decided yet, and will see how things play out after the fork,
If you buy bitcoin on Coinbase, you need to be aware of this. I suggest moving your bitcoin to a wallet where you hold your own keys before the fork.
