Several altcoins have outperformed BTC in different aspects. I am thinking that it might catch on but I collected and sold my BCH quickly as I could. It is still over-valued. Dash seemed like the real "currency" to me but the Dash team is not doing all it can and a full node has to hodl 1,000 Dash. Every coin has its problems. BCH takes hours to make a block and I am glad I bought 1/4 of one BTC with my 2 BCH. Decided to spend it on food, booze, gifts, and electronics. BCH might have some advantage over the original, but probably not to the tune of 3,000 USD. there's value, but it's to early to discern.
