I am on my Bittrex account, wanting to deposit btc for this ico. This message pops out when wanting to deposit "Do not whitrdawal directly to a crowdfund or ICO. We will not credit your account with tokens from that sale". I know that when the withdrawal will take place from the utrust website it will not be on bittrex nor in btc. But I still want to be sure that they do not "lose" my btc while depositing.
In need of help

Well after you have deposited BTC to Bittrex you need to BUY Ethereum ..
Once you have Ethereum you need to transfer it to your own wallet ... I'd suggest you use
www.myetherwallet.com and create one there.
After you have created the wallet on myetherwallet you need to transfer your Ehtereum to the myetherwallet adres.
As last step, you need to send your ethereum to the ICO address of UTRUST.
After the ICO you will receive your tokens on your Myetherwallet.com
