I just opened this web3 gambling site and yes it's quite interesting, and it's like trading for me it's just that your risk your reward we can't set it ourselves, there is something I want to ask that it seems that this only has a time limit of a few seconds to place a position and then will get the results in seconds, is there an option to set the time? it's very difficult to gamble with second bets, and of course I want to know the benchmark bitcoin API price that you take from where?
Well, I don't know but I think they may likely not allow the possibility of gamblers having to choose or set their own time, allowing such is not possible for several reason, and one of those reasons is that it may open the door to manipulation.
That is, a gambler can bet on that price of a coin, choose a Time by himself, and then proceed to manipulate the price of that coin to make it worth exactly the same as his bet at that particular time he choose, which will give him an instant win.
You may want to say "how is it possible for a person to manipulate the price of a cryptocurrency", people with lots of money can do this easily.
And as for the exchange where the casino draws the price of cryptocurrencies from, that I leave for the rep to say.
Yep your opinion is very reasonable, that might be the reason, but with such a large bitcoin marketcap it is very difficult to manipulate, not to mention crashing sell orders at certain price levels and can be reversed, btw from my experience and in this feel it looks more like a Binary Option where it is very similar to guessing up or down in seconds.
