What people should do who holds luna in exchanges?

I hold Lunas in binance, what should I do to get the new luna airdrop?

And I could not buy because I was already ran out of money I managed to hold 19500 luna at average of 0.54$.

So I probably will never get back my investment, people who are buying billions tokens now will be the gainers!

Anyway how do you claim the new token on binance?
