Gotliv - The answer will largely depend on your GPUs
Equihash - Zencash and ZClassic are probably most profitable right now but keep in mind equihash ASIC miners are coming soon.
Lyra2z - ZCoin. Not too sure about current profitability but they will be changing the algo soon. Coin is at $22 now but was up to $140 in December, so I think sooner or later it will climb
x17, lyra2v2, blake2s - Shield. Initially a clone of Verge but I believe a better dev and a large community. Was at 33 cents in December, at about 2 cents now.
cryptonight - Stellite, Intense, and Monero. Stellite seems to be the most profitable lately. Special shoutout to Intense coin though, as I think they have a great project. Its just slightly less profitable. Monero usually isn't the most profitable cryptonight coin to mine, but its the most stable for sure.
Try NCP cryptonight algo, new coin with many investors coming from xvg community. and will be a huge just like BCN i think, you need to check it out.
