if u don't have much tokens then it better u just buy 3-4 stars,never go 5 stars no matter how old is he.About the bidding,at the beginning u just have to bid 1 time(usually bid at the last 1min)and then when the knock out round come,1 bid is enough since u just need to get qualify for the next round,and from here come the strategy:so let assume that there are only 2 bidder,u and the other,and both of u are at the 3th knock out round going 4 the 4th round,the other bidder now quality as leader(green color)and if u don't make a bid to quaify 4 the next round he then will win(and he don't need to bid to qualify 4 the next round either,cus he already a leader).So at this point wait till the last 1-2s and then bid,sometime ppls might think that u're out of tokens(or just give up) so they don't make the qualify bid and they just lost like that.but sometime the other just have alot of exp bidding then now it only a matter of who have more money and tokens,if none back down .I myself 1 involve in the bloody bid up to around 70 round ,and i had to give up(if i didn't do it i think we both gonna go till the end lol ) cus the player cost just go way to much compare to his true ability
