Trident Crypto Fund is a Cryptocurrency Index Investment fund. They launched their website and airdrop in May but there's still time to claim 1 TDC worth $2.46 at the time of posting by registering for free on their website:

The Trident Core Windows desktop wallet was released Oct. 11th you can get it from the link on this article:

You can also claim 1 TDC for each free referral you get.
Personally I haven't invested in this fund, and I would urge you to do your own research before you consider it, but free tokens are free tokens so there's no risk there.
Permission.io is a brand new social network launching at the end of the year that is currently giving away 250 of their tokens to new users. Simply sign up for free using the link below and the referral code 2WLZDJ to claim your free tokens, and for a limited time you can earn 2500 tokens for every free referral credited to you. How much these tokens are worth is anybody's guess but they're free right now so why not grab some while you can.

I'm always on the lookout for crypto giveaways and referral programs, and when I find them I send them out to my mailing list.
