I'm in the same situation and decided to get the D3, I got it from bit main and used some of my NEO profit to buy it so didnt feel so bad spending the BTC. Im in the mid nov batch.. I figure if I can make back the ~0.3 btc over 4 months and then 1btc in one year and learn a little and have some fun doing it it would be worth it and will probably lead me down the miners rabbits hole.
I wan to mine and hold some dash too as it's stable and I see some long term growth there with BTC/BCH hard forks, segwit and all the splits that may come
