A whole bunch of useless shitcoins, most of which aren't even listed on coinmarketcap. Honestly you're better off spending your time doing regular faucets instead of this, eg. coinpot.co or faucethub.io.

They recently added Dash but from what I can tell after trying aircoins for a bit, there are no Dash to collect after trying multiple dozens of locations. YMMV, seems like a complete waste of time for me IMO.
