I guess in near future they may have another hard fork to have another coin like what they have done for creating bitcoin-sv. This way they may keep on air-dropping new coins to have new investors on board.
Like what Tron was doing with Bittorrent airdrop ? But, I am not seeing any of these will be helping these coins in long term. People are always looking for actual growth not just these free stuff. It may be a short term quick triggers but not sure how intensively it may help on long term basis.
Bitcoin cash may survive in my opinion too due to their continuous bumping scenario. It may be from the devs or from the people out of world too. But, when they keep on bumping, they may list on top in coinmarketcap which is the reference for many people here to trade and to invest too.
