When enough SBDs are funded - so a rig with 3x Gf 1080 probably. The fund raising could last a week and when enough SBS are garhered, no new investments would be accepted. What do you think?

So investment for round one stop at 120-150 sbd. I like it. Is it safe too invest now?

Yep :) I won't be doing any SBD -> Fiat exchange until there is a really high chance for the funding to succeed. If it fails, of course all SBD will be refunded. So, it's time for pubic announcement?:)
