this three points just want phase 2 BTCs?
From my perspective all looks like show from DEVs who want as much money they can without any real work
,once BTC they got then they disappear. Ghost devs behavior is really fishy and puts me in concern that is a classic scam.
For future investors devs where they refuse to work are big red flag also paying bounties like translations and signatures are out of question.
Most honest people pay for work their workers after work is done there is no needed condition besides you need your work to be done.
What is a difference if you pay 7BTC from 1st or 2nd phase ICO ?
If you are worry that 2nd phase investors are risk free that is fine
but that is a reason of those guys that they use escrow to be risk free
that devs will take money and go away never delivering something.
I would divide costs of exchange listing 50%/50% that 4BTC it costs after delivering but not 30BTC.
After delivering working beta wallet 50% after credit cards rest.
We were paying for such features using escrow if we don't need them then escrow users can go bittres and chose random POS coin
while output will be the same.
The amount of black PR delivered by DEVs is enormous.
Without 2nd phase BTC project won't go probably anywhere
and credibility will be almost close to 0.
I full agree with SJ that you need deliver something as DEV proof of work not only coin generator wallet putted on some exchange.
