In 2017 there were two factions of bitcoin supporters, those that supported large blocks and those who preferred small blocks. The Bitcoin Cash faction favors the use of its currency as a medium of exchange for commerce while the Bitcoin-supporting faction view bitcoin's primary use as that of a store of value. Bitcoin Cash detractors call the cryptocurrency "Bcash," "Btrash," or "a scam", while its supporters maintain that "it is the pure form of bitcoin".
Samson Mow of Blockstream pointed to Bitcoin Cash's use of the "Bitcoin" name as a source of animosity between the Bitcoin and Bitcoin Cash camps. Emin Gün Sirer, a professor at Cornell stated that Bitcoin Cash was focused on use and Bitcoin was "enormously" focused on store of value.
