The Bitcoin clones will get a bunch of miners for a while. And some pools will see switches. Whatever gets the most profit will attrackt the most of the miners.
Do not know if any of the clones can be put out off order just like that. They are pre-sold on exchanges and traded on. That is a trick to give them value upfront. That will lure in some miners too when it goes live.
There are some very rich forces behind some of these clones. B2X might even be the last of them clones that maybe manages to loot some value out off the real Bitcoin price. But I think the Market is slowly getting fed up with this cloning nonsense.
As for mining other coins. DASH and LTC are mined very hard. And they are not the only Alts getting a lot of mining power. So, I think the whole cloning farce will end soon after B2X has become just another kind of Altcoin competing with Bcash.
And the rest of the market wil have enough Alts to mine and new invested capital to gain.
To me the whole crypto future is bright.
