I am around $6-$15 per day for months now - Average is right around $10. I use awesomeminer with miningpoolhub and nicehash - all algo's are configured that each pool has available - automatically mine the most profitable algo/pool.
So to me, yeah it's worth it, and if they actually add new algo's again, that will extend the life of BK-X profits.
Only thing I do not like about Baikal is that horrible website and doing things via email and Skype - please get a real website with shopping cart etc. It would double their sales - took me a year to finally order from them...
Why use only miningpoolhub and nicehash?
Just because I like to receive BTC at times and you don't want your miner changing too often, the brief down time during the switch and the lost shares from switching pools (depending in type of pool payout) and actually harm you compared to staying within a smaller pool size. I should mention, I do not have x11 as an option.
