Well this is exhibit A (if they are using the Ethereum blockchain network) why Ethereum Classic, LISK, NEO, and NEM and Cardano (when complete) will offer scalable and less congested solutions for new projects and ICOs. I was a member of the Crypterium ICO (ERC20 token), it took well over a week to 10 days to get my coins once they took them from their wallet and transferred to me.

I guess my point is I place as much of this on the network...however, from this point forward coins need to understand using the ETH network could spell congestion and delays for mass distribution. Neblio is working on this as well...
