It actually works and I'm receiving tokens.
Just sent 0.001eth to see if it checks out and it does. Cool.
I noticed that you yourself are mining too and that we're finding the same blocks at the same time now and then. The TX fees are lost if you're a microsecond later than the other guy, so what happens when 1000 people would mine this?
Difficulty will exponentialy growth and aslo mining pools will manage these conflict under the hood. It is a normal behaviour on any coin, here it cost and extra transaction but it come with the design.
