What is the best way to convert ZEC & ZEN to BTC?

[bdog1234]

I am mining both ZEN and ZEC but prefer to hold BTC. I have been trading them on bittrex. Is there a better or cheaper way?  I have also been trying to determine the best frequency to do the exchanges. I am mining about $50 a day. Should I exchange daily, weekly, only when rate is favorable?

Well it depends, if you need the money as soon as possible then exchange them just when you have them in bittrex. but it does not even take a high fees for that... only 0.50% per exchange at least.. so it does not make any difference between doing it daily/weekly
So there is no a cheaper way to do it since you are gonna do it in one of the most used exchangers, and that is why it is cheap.

The cheaper way would be by using an exchange just like you are doing now. There is really no difference on when to sell besides seeing the price at the moment - that may vary. So, you could sell once a week and get lucky to do that when the price is higher, or sell once a day, when the price is down.

If I was only mining for the profit - and not to hold the coin in the long term -, I would sell them asap, since price is most of the time also influenced by the mining difficulty.
