They're both often at the top tier list of most profitable algos. Better than zcash & co most of the time.

Sometimes during the day they're low, like right now, but other times they're pretty high (8-10$ profit), i switch on them more than 30 times per day (each switching slot is 10mn) so that's about 25% of the day they're the most profitable.
