IMHO it is just the natural process to end up having just the original BTC over the rest. If you take a look at all the BTC forks which took place last year, BTC Gold, Diamond, Private, Superbitcoin, etc... None of them has gone anywhere except for BCH which now just entered a civil war with a new fork which could end up killing its value.
It is just a matter of time until just the original Bitcoin is the only one in the markets.
