Definitely missed out this AirDrops due to lots of schedules, and I see great potential from it. I really recommend this project. Too bad am getting this late.
I thought I was too late, then I realized that they have pre-trade mining. It is basically trading in their exchange and 100% of trading fee incurred becomes PROB tokens. Sounds like a good deal, considering the amount of airdrops they are giving out! Definitely one of the up and coming exchanges around.
