I posted a bit on Urbit myself. Their crowdsale went so fast that it seems no one but insiders had a chance to take part. I knew about it and still couldn't get in because it all happened in mere hours.

I was lucky to be online and picked up a few extra stars when I saw how quick they were going. I think I will re-sell some at cost here on Steem soon, keep an eye out!
Good, will consider buying when that escrow feature is set up.
