Im sorry these are both shitcoins. If you want a privacy bitcoin fork, they why not just go for bitcoin dark. It has zero development too but the price is going up atleast.
bitcoin dark is being swapped for kmd komodo. well it was that has finished now. so if you want privacy then kmd is the coin to be. take a look at barterdex. decentralised exchange with atomic swaps. btcd will be gone soon
