I don't like so much bitcoin fork actually. If i want to show some interest any of them then i would pick BCH, nothing else. Other's coin are not to much worthy for me. You are right on your point that those coin can pump if bitcoin will pump (in halve). But why people would choose those fork coin over bitcoin. And there is still lot of altcoin better than those fork coin i guess. ETH, BNB, LTC is more worthy for invest than any bitcoin fork coin.
