Don't worry, they tweeted:
Current state is that some TXs might not show up in the HOQU back office after investing ETH/BTC/LTC due to clogging in ETH network
If you had everything processed but the info doesn't show up - do not worry, we have all the info and TXs are to be shown on 11 of Jan, not sooner.

The teams communication is assuring and the ICO looks very promising. If you decide to participate: https://www.hoqu.io/?ref_id=0c1d51f3465bda51aac7f3016f84a20e
