This, it says, is because SegWit2x “does not include two-way transaction replay protection, enabled by default.”
“Therefore BitMEX will not be able to support SegWit2x,” the announcement states.
“As such, BitMEX will not support the distribution of B2X, nor will BitMEX be liable for any B2X sent to us.”
The exchange requests customers looking to receive 2x coins to withdraw their Bitcoin holdings from their accounts prior to the network snapshot in November.
What about other hard forks
Like others’ announcements, no explicit reference was made to the other hard fork due next month, namely Bitcoin Gold, BitMEX saying its position applied to “any and all potential hardforks.”
“BitMEX considers any and all contentious hardfork tokens as altcoins. The .BXBT and .BXBTJPY indices will remain unchanged and will not include B2X,” the announcement concludes.
As SegWit2x continues to cause rifts throughout the cryptocurrency industry, anti-SegWit2x commentators reacted favorably to BitMEX’s decision.
WhalePanda, a Twitter personality famous for his frequent opinions on cryptocurrency news and events, even endorsed the exchange, publishing a referral link for users to sign up.
