What do you think, why Bitmain accept payment only in BCC, that is not because they like BCC, they invest there where can get bigest profit.
Incorrect. They accept BTC, BCC and LTC

You are wrong last two batch only BCC. But that is only small part of this discussion.
maybe, but you can see right now they are selling for BTC, BCC and LTC
It's amazing how stubborn some people are, instead of just checking the website, some people prefer arguing and misleading others.
Right now from Bitmain's website:
Payment
1. Only BCC(Bitcoin Cash) payment method is accepted in this batch
The same was for the last 3 batches
BCC is Bitmain's coin, why would they support others...
