am i only one who cant find any bets on this site
No you are not the only one. There have been none for three days since I began checking. Maybe they are off for the holidays or maybe nobody uses it so they have not put a lot of effort into adding the lines. I was trying to get some XCP to see if I could figure out how to write a bet. It seems they call it a 'feed broadcast'.
i have some XCp in my wallet around 0.25 xcp but they charges fees in bitcoin every time to send any payment
Yes you need small amounts of BTC to make a XCP transaction which is why I think Ethereum should be a better implementation of this. though, I am impressed with what these guys have done so far.
