Lol this you just edited your post
but yes it's 0% house edge but it's really hard to win, If you I already visit the site and i saw lots of user send so much bitcoin just wasting money for nothing you need there is luck too,
And if gambling website offered 0 % house edge there will be win in everybody 
0% house edge does not mean everybody wins. It only means that in the long run house and players have the same possibility of win. Generally, 0% house edge is offered by new games to attract more players, which is probably the case here. If u want to take the advantage of 0% house edge in this game, then better bet on multiple options at a time to increase your winning chances.
Whatever the house edge is you cannot improve your winning chances unless you are able to modify the house edge itself, by using a strategy, valid in some games, or somehow hacking the website which is illegal.
