I have like a more then one month experience with GM.
I bought contract with promo code and I was happy. I can say, that there is a good support I like the GM portal. I found answers to my questions here as well. I like this approach.

What I did not like is the how my investment went to the red numbers. Here is chart showing payments since beginning of my contract per 1GH/s:



I left my mining allocation on AUTO (BTC) 100% all the time.

What is your experience and can you recomend to switch from AUTO BTC to  try get back from red numbers?

Thank you
