it is obvious that the coin can be cloned like any other, just copy and paste the code
The question was another.
It was about a split in blockchain as happened with eth / etc.
This is impossible in decred because the blockchain stops working without POS voting that will always be directed to only one chain.
This is interesting, although I admit I still don't understand how it is impossible to make a chainsplit even if it does indeed take more work than I assumed before.
But if you insist this is the case and the dev team agrees, I guess I'll take your word for it
