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...
