So, lets say you've developed a new altcoin and you're going to do an ICO. How does escrow protect coin purchasers? I mean, the dev team is eventually going to get access to the BTC at the end of the crowdsale, at which point they could just steal it all.
In my opinion, once a product, altcoin in this case, has been developed there is no logic in using escrow. The developer should receive all the raise upon development. Escrow may be needed throughout a development stage to essentially incentivise the developer to complete the project before it gets all the ICO-raised funds.
