It is quite profitable! actually one of the most profitable coins right now. 1070 gives 20 MH/s and 1060 gives 13,5 MH/s (i have both)
With 100 MH/s you get little over 1 BTX per day now... if you also calculate airdrops every monday it is a very nice result. Even with the price BTX is now... but it is expected to go all the way up, so in that case mine now, be happy later Best is probably to buy some BTX now because it is relatively cheap, so you have some good earnings by airdrops every monday + keep minning so you get more.
