On December 12, the Spark airdrop will be held for those who hold the ripple coin. These tokens will be distributed in the ratio 1 XRP = 1 Spark. Some exchanges have confirmed their support for this airdrop, for the rest, I recommend reading in the blog how you can get Spark tokens: https://flare.ghost.io/claiming-spark-faq/
I had not heard of this airdrop before, but I have some XRP so why not make use of it
. As tvplus mentioned, binance is first big exchange that is supporting the Spark airdrop. Hopefully some other major exchanges (Kraken, Coinbase,...) will also support the airdrop.
