Oh yes it is really nice catch.It seems op has invested more than 0.2 btc,why he wants to sell it for less that what he invested?Is he planning to sell same thing to multipple users?
The catch here I find is, all in your imaginations. Where did OP says the b8ball project is for sale dude ?
The b8ball project did was not a success for reasons unknown, but was anyone scammed by the devs or the project ?
I did not find any scam accusation. Even if he tries to sell a project which he has abandoned, what is wrong in it?
