I'm a big fan of this project. If I had more money to risk on speculation, I'd have signed up for the presale. Commercial shipping is a HUGE market, the ShipChain team is stellar, and the solution is a great fit for the problem.
I think they require $5,000 minimum for the presale. I can't afford to lose that much money speculating -- if you can, I recommend giving this a shot. Could be YUGE.
$3,000 minimum for the pre-sale according to their Whitepaper.
What do you think the theory is behind setting the minimum so high? That's almost wall street buy in money.
I don't know. @sephiroth do you?
