1. The point is you don't want to store the coin. I mean you can if you want. But I firmly believe in auto converting to BTC as the best option when mining. It is the safest way to protect your profits. If you then want to turn around and invest in certain coins you can pick your moment and buy when the buying is good.

I do use Jaxx wallet but generally not for storing coin.

1. Suprnova is decent but has had issues I prefer nanopool but either would be fine.

2. Good advice. This is what I do too I will add a line to my blog as I figured most people would just do it that way without being told.

3. Solar would be amazing. I just don't have 20k to drop on it right now :D
