I've watched the previous crypto conferences pass by and a lot of coins getting donations and/or using premine to have a representative there. Most of those coins were just completely skipped and barely got any attention at all, let alone that their popularity increased. What makes you think it will be different for curecoin/this conference? Do you think an expensive conference booth will be more useful than using a donation fund to get listed on a site like Coinpayments or another payment platform to get more uses for the coin?
(not trying to bash your idea, I am just being critical before sending my money to a stranger)

P.S. maybe you can also add a CureCoin donation address
