This is what i was also thinking . i missed the UNI airdrop but managed to get it from binance once it was listed . why not send it to Huobi for additional 50$ as op said.
I have also participated in this event but at the announcement of this event and the UNI gets a pump to its ATH. If you were participating in this event and you will not get only $50 as free money from your UNI but you will get the advantage caused by the increases that happened in the market too.
That means you will get some advantages from your UNI a free money from huobi and from your UNI.
I hope there will be another good event like this one too.
