Im going to invest a couple bitcoins into this but Im not going to have them until the last day. People are just waiting because normally IPOs haven't lasted this long. Everyone buys in on the last day because it gives them a chance to see if the coins and its devs are legit.
LOL it's because people like you who share the same view IPOs don't last long. If everyone buys in the first place, the quota or threshold would be filled immediately. Just saying!
