Difficulty with DASH is really "sensitive" . I mean, a small increase of difficulty makes a machine bleed!

What i say is right now, you can make 7800$us ( today ) a month with a D3 with a difficulty of 414,000 .

If the difficulty goes to 850,000 in september after the first machines are delivered, you will make 3800$us with one D3.

Imagine if the difficulty spikes to 2M by the beg of Oct... that's 1500$us/month...

And im saying this because right now, we have seen difficulty above 700k on some days... so double or triple that when machines are delivered is almost obvious, if not a lot higher....

So i am not sure if it's cool to purchase more D3 if the batches are for October-Nov....
