Is This a Trustable Airdrop?
Yes, the airdrop is trustable. However, if you are new to the Farcaster platform and Degen chain, please do your basic research to get a better understanding. 
One of the users lost 90% of the funds while using the Degen Chain Bridge. However, the Degen devs have immediately developed a solution to retrieve the lost tokens. This shows their commitment and genuineness.  
Also, after this season, DEGEN and Farcaster will come up with more exciting airdrops. Follow them to participate in all the upcoming airdrops.
