Dicing and Flowers is stupid, less than a 45% chance of winning plus a chance of being scammed on top of that.
I made 70b on a staking pure and got 100% cleaned. Ended up rebuilding to 110b from scratch and sold it all for 55k. After that rebuild to 65b again and sold some of it before being cleaned once again. I am cleaned at the moment, there are not very many people at the duel arena these days and the ones that are there either know what they are doing or are poor. Just don't give up, and if you want to gamble please don't do that flower/dice garbage.
