Don't know what you asking, UTrust has their own ERC-20 token, this means that you can store theme in any ETH address of which you own your private key
Can you send from exchange or only MyEtherWallet?
Never invest directly from exchange - you need to be in posess of private keys. If you invest from exchange you will probably loose your eth/tokens. Best way to contribute is to use wallet like MEW, metamask, etc.
I think utrust ICO works similar to the tezos ico. They have their own individual eth or btc address and wallet for each contributor then you can transfer your coins to which ever eth address that you like to transfer your coins. In that case I dont think it will be a problem to use exchanges wallets to send the eth directly to the ICO wallet. I will get more clarification from the team regarding this.
Yes, it turns out that it is allowed for this project.
Terms and Conditions :
You can send ETH or BTC from Coinbase, Poloniex or any other wallet even if you don't directly control the private key for, you will be prompted to insert a new address that you control at the end of the ICO so we can transfer the UTK tokens.
