Finally, the guy who recommend for buying BTC seems to be charging approximately twice the current market price:

Maybe reconsider encouraging such massive overcharging and find a more reasonably priced trader to advertise.
As for this, the advertisement is not a buy and sell location- there are others for that, its just to have a message launched from the profile to prove he is backing us.
good design and very interesting, but I do not like the Auto bet using the pop-up menu. I can not see my balance is reduced or increased because let me know I get a profit or not of the auto bet

Can for the auto bet if it is a setting in the menu ghost could play a direct play and roll without having to see the pop-up menu

You can close the popup menu with the button "close" located next to start the ghost.
