I LIKE THIS!!!    I love it the way it is, however I think it could be refined even more!  You deserve cookies!

It does. You may opt out for any reason you wish or even with out any reason at all. However i will not speak to the morality of backing out even if he delivers on all of his promises, that's for you to decide.

did terms of escrow as described by OP allow for pulling out?  I would think that unless specific terms were in there allowing bailing out, that a REAL escrow service would hold the funds until "eXo was sent", then would disburse the BTC to OP.  This is the definition of escrow.

And when I use the term "eXo was sent" I would expect eXo to be sent directly to purchaser, not through escrow service, since escrow service can check blockchain to see that eXo was sent.  Also by the term "eXo was received" the eXo I refer to BETTER had some advanced features available to make sure we can tell the eXo product isnt just some closed source clone of existing coin.

Can I buy his early investment?

Oh, I'm a fool. errors one by one.

I Read the whiteparer and apparently is legitimate.
I'm web developer (php mysql flex), do not have such an advanced understanding in cryptography to guarantee anything.
Waiting for the next versions with more technical details. The UML and code is coming will help evaluate better the developers plans.
But the paper -> UML to get to software is a hard road. The paper accepts everything.
I'll wait for the scenes of the next chapters.
:p

Did the second stage start yet?  I think I'm like 3rd person to ask this in the last few hours with no response.  It doesn't seem like a difficult question.

Yes?
No?
When?
How?

No, it has not started, the dev is waiting to organize before launching 2nd round.
