With all those millions usd potentially rise they just need to pay 1k usd to one person and will be happy to send manually email reminder every day prior launch.
I'm starting to think there is something very weak behind this delay....
If dev are busy with code, just pay someone's to send reminder.
They wouldn't even need to send email manually. They could have automated the process sent all the emails out, in bursts, within 30-45min tops. Hell, they are targeting JavaScript developers and there are plenty of node developers interested in the project that would have taken 5 minutes out of their day to throw together a script to do just that for them.
