I have been a little bit wary of this.  I joined for the airdrop and I got my tokens.  I have the wallet and I use it to access my secured keystore.

I have been concerned about the possibility of theft, since the app could easily store the keystore file and capture key strokes to get the private key to unlock it.

So far so good, though.  I have been getting about .5 token per day after the 10-day hold.
