Without utility, there's no "value" to be released when you're done storing it. This whole "bitcoin is gold/store of value" meme is based on greater fool theory.
BTC holders are basically just waiting for someone else to come along and pay more money than they did for their useless internet token, and that person will only be buying in the hopes of doing the same.
Meanwhile, BCC continues to be sound money, just like Bitcoin was from 2009-2016.
To clarify, being sound money and a store of value are not mutually exclusive, but rather feed off one of another in a virtuous cycle. Bitcoin is a good store of value because it is good money, and it's made a better form of money because it's a good SOV. Removing one side of the equation doesn't maximize the other, you're just left with useless tokens either way.
