wait and see. I think that people invest again in Bch. because it's not about btc, it's about making money
And its in BTC the most money is made yes you can make money trading with these alts but long term BTC is where the real value stands
that entirely depends on where original-BTC is going: if it continues deviating from EVERYTHING it originally stood for, not much "real value" nor any "long-term value" will be left in it -- as it is based on user appreciation only (no real 'intrinsic value'
in the classical sense, so it rises based on scarcity only=if demand is larger than supply, which is limited to 21m as we all know). With BTC's politics influenced by AXA insurance group and similar interests, its failure (as BTC-the-coin) would not be much of a loss to this world. (Bitcoin-the-technology will continue in the form of BCH, LTC ETH, PPC, XBC, DASH -- and likely even DOGE -- and everything deservedly representing a true, decentralized, peer-to-peer i e REAL crypto coin!)
On top, BTC's latency/mempool/congestion/high-fees problem is currently back to pre-August levels. So, no, original-BTC's problems are far from solved. (Satoshi-Lite and others similarly in the know told us so all the time. Turns out, they were right.)
If other coins seem to fulfill Bitcoin's original promises better or in a more appropriate way, demand will move to such other coins. It's a free market, plain and simple, and that's what free markets would (should, will!) do... Yes, exactly BECAUSE it really IS about where the most money is made.
