It's funny to watch how crazy this whole thing has become. People want airdrops, free distribution etc. AND proof that this is not a scam.
It makes financial sense for you as an individual even when adjusted for risk, but it hurts the crypto community generally because bad people everywhere in cryptoland will see what they can get with just an ANN. That being said, I am really interested in STONE if it happens likes most people here, I just prefer to remain very skeptical until there is evidence of an actual coin, not just an ANN.
Check out the NXT and NEM topics here, what evidence they had and where they are now.
But I agree that it would be better to use an escrow anyway.
An escrow will at least help show the dev is upto some good. Although funds can still be stolen from escrow wallet but then again it's still a good move first.
