so i'm saying they used their own bitcoins to buy into the ico and sell the free waves cheap, will they deny it also?
and once they deny and i can prove they are lying, what do you think will happen?
This is obvious that they had their own BTC put in the project and anyone who thinks different is deluded. If you have proof then I suggest you make the community aware because as it stands they will neither confirm or deny so you will be waiting a long time if that is what you are waiting for. If you have proof then proof is proof and it doesn't matter whether they deny.
To be honest I very much doubt he is able to which is why he is acting strange and beating the bush with it.
that is not how the burden of proof works. You've got proof, show. What's the point of "catching" them in lie? If you got proof then your fact will speak loud enough.
