Depends on how many people did that and what their intentions are. Also to sell 8mb bitcoins, a >1MB mined block will have to be accepted by the network which may not happen for hours or days. There is a schedule for difficulty changes but there's no telling how long it will be before they are actually tradable.

[I was definitely wrong here] UAHF specs that the fork happens after the 1st >=1MB block is mined. https://github.com/Bitcoin-UAHF/spec/blob/master/uahf-technical-spec.md https://github.com/Bitcoin-UAHF/spec/blob/master/uahf-techni... But it looks like the "fork" is already happening, because Bitcoin Cash network rejected block 478559, and now has to mine one of its own. 2017-08-01 13:23:46 ERROR: ContextualCheckBlock: BUIP055 fork block (00000000000000000019f112ec0a9982926f1258cdcc558dd7c3b7e5dc7fa148, height 478559) must exceed 1000000, but this block is 272502 bytes 2017-08-01 13:23:46 ERROR: ProcessNewBlock: AcceptBlock FAILED 2017-08-01 13:23:46 Invalid block due to bad-blk-too-small 2017-08-01 13:23:53 ERROR: AcceptBlockHeader: block 00000000000000000019f112ec0a9982926f1258cdcc558dd7c3b7e5dc7fa148 height 478559 is marked invalid

  // If UAHF is enabled for the curent block, but not for the previous block, we must check that the block is larger than 1MB. https://github.com/Bitcoin-ABC/bitcoin-abc/blob/174846aaaf564e64b6bd06d679996b52ba86ad53/src/validation.cpp#L3397 https://github.com/Bitcoin-ABC/bitcoin-abc/blob/174846aaaf56...

    That's very interesting, thanks for linking to the code. Why would they require the first block to be >1MB?

      I think if the block is >1MB, then that's at least one indication that BTC cannot possibly include it in its blockchain, and thus is a new blockchain entirely.

      It's to make sure the block will be rejected by the non BCC nodes. This way you have a "clean cut": the Bitcoin Cash nodes rejecting the non-BCC blocks while segwit nodes reject the BCC fork because it starts with an invalid >1MB block.
